For a hobby I build high powered handheld lasers, they are usually in the visible spectrum. Recently I got bitten by the gun bug and have become almost addicted to firearms (living in MD and having until 10/1 to buy what i want doesn't help either). Now I am trying to combine two hobbies :)
The laser I am about to show you are built by me for me so there is nothing illegal. http://i1309.photobucket.com/albums/s636/mhemling33/Laser/IMG_0242_zps512c2c8b.jpg http://i1309.photobucket.com/albums/s636/mhemling33/IMG_20130423_211606_zps75d08ec9.jpg http://i1309.photobucket.com/albums/s636/mhemling33/IMG_20130423_211554_zps49c65134.jpg http://i1309.photobucket.com/albums/s636/mhemling33/IMG_0222_zpsfe075060.jpg Here is a video of one http://youtu.be/sRsv3K35_Do So now here is my reason for posting this.... I am now interested in creating high powered infrared lasers for night vision purposes. I currently have built 300mw and 1000mw 808nm IR lasers but since I don't have night vision equipment I have only been using my phone to see what it can do. Seeing the price you guys pay for <200mw IR lasers they can be a fortune, but is there a need or use for 1000mw-2000mw IR lasers that you guys can think of. I just don't want to devote a bunch of time to something that has no use. Would a high powered IR laser be better as an illuminator or marker for you guys? Thanks for any input! |

Such a powerful laser is going to be useless with NVG's unless you trying to light up an area and wash out people's NVG's Well I was eventually going to attempt long distance night vision.... and before I waste alot of time and money i wanted some input and who better to ask then people that use it |

My .7mW OTAL is more than enough to engage targets to 400+ meters. Maybe 2000mW could be a laser designator for our resident space shuttle door gunners?  LOL that would be a hell of a shot. I am trying to future proof society ;) I was thinking about those who like to go long distances like .5-1 mile range. What if I could make something with variable modes of power with a max of 300mw? All of my lasers have adjustable lenses so you can go from a really small dot to a large circle. I was wondering if you could use the large circle like a concentrated illuminator, the further away the bigger you can make the circle. |

Have you ever scavanged the BluRay diode out of a PS3? Yes you are looking at 100mw tops with the stuff out today it is no longer anything impressive. The funny thing about bluray is it's purple. 405nm to be exact. For more powerful lasers can harvest them out of Bluray burners 12x with these you are going to get anywhere from 400mw-800mw depending how hard you push it and what lens you use.... Here is my laser from a 12x bluray burner it outputs almost 600mw off of 2xAA batteries ;) http://i1309.photobucket.com/albums/s636/mhemling33/IMG_0041_zps29ffd5f3.jpg Also there is going to be some very nice green sights coming out in the next couple years because of a direct green diode OSRAM has manufactured here is a picture of it in one of my builds http://i1309.photobucket.com/albums/s636/mhemling33/IMG_0042_zps88fb6344.jpg |

The 5mw versions are already good for like 2,000 meters, something like that would be retarded overkill as a IR laser. That's like asking if 9,000 hp is reasonable for a daily driver toyota corolla. I'm no IR expert, but I'm having a hard time seeing where something like that would be useful in a handheld role and not strapped to an F18 designating targets for bombs.

OK thanks for saving me on that one. I just assumed that because of the legal limits they might not be taken to their full potential but it seems that their is no need to go crazy with power. Quoted:
I have a dead PS3. Is the diode easy to dig out? If you were going to be attempting to replace the diode.... I think it would be better to find a refurbished sled. I believe you would need to calibrate the diode for a certain output to work correctly. If you are going to build a laser using the diode... It is not that difficult. There is a lot of material on how to get to the diode and make it a laser. There are two different types of diodes depending on when your ps3 was manufactured. Here is a link that would help you with what to do. KipKay If you just want a purple laser pointer i highly recommend one of the $5 ones of of ebay they are always way over spec (says 5mw but measures as high as 100mw) Ebay 405nm Pen |

I like your silver one with the BluRay diode.
I was thinking it'd be fun to convert a Mag-Lite, but yours looks a lot nicer! I have no talent for such things, so I'll probably pull the diode and give it to a tinkerer (so it doesn't go to waste) then buy a laser pointer. |
|
Also there is going to be some very nice green sights coming out in the next couple years because of a direct green diode OSRAM has manufactured here is a picture of it in one of my builds
If this is for sure, it will be a huge breakthrough for weapon lasers. Red lasers would dissappear overnight. All I can say, is I hope you are right, it's about time! |

Yeah I am for sure ;) Like I said before just from a hobby standpoint these new direct green laser diodes are a huge deal. Since prior to this the only way to get green was to pump an infrared diode through a set of crystals which changed the wavelength to green. This means you had to have room for the crystal set, it couldn't convert IR to green in the cold weather, sometimes things will become misaligned and at that point might as well throw it away. Here is a size comparison of the green DPSS (Infrared through crystal) and a 3.8mm diode the same size as the osram direct green. http://i1309.photobucket.com/albums/s636/mhemling33/rps20130619_173940_582_zpscdd806ba.jpg Here is a close up of what I mean about how a crystal system has to sit in front of an infrared diode. in that spacer there is actually a little rectangular crystal that does the conversion and then the top lens helps correct the dot but it still needs to pass through another lens for total correction. The direct diode has to pass through a final lens too but you don't have the other stuff! http://i1309.photobucket.com/albums/s636/mhemling33/rps20130619_174306_533_zpsf41d3cfc.jpg For you guys that use night vision and a green laser sight and you can see the dot through the night vision scope..... you wont have that anymore. The dot you are actually seeing is infrared that had passed through the crystal and didn't get converted to green

The dot you are actually seeing is infrared that had passed through the crystal and didn't get converted to green Wow, well that's cool. So this new green diode won't have the low temperature issues like the current ones have? Also, with that 405nm pen on Ebay, how do you know that the output exceeds 5mw? I'm guessing you have a laser power meter. What sort of power reading were you getting? I'd like to buy one of them, but I'd probably avoid it if it's approaching 100mw. |

Depends on the tube. GenII can usually see 400nm at about the same sensitivity as 700nm. GenIII is typically 600nm to 920nm. |

Yes this means no temperature issues :) As for the pens they all say 5mw and you don't know what you are going to get, so don't ever believe what they put on the label. I have an Ophir Laser Power Meter (LPM) that I use to measure the lasers and get their actual outputs.
If it can see red that is because it is very close to infrared. The current green lasers are made from infrared lasers and what doesn't get converted to green is what you see in your night vision because it is still IR. But as the post above me says it all depends on what wavelengths your night vision works with. Now for the big news! I finally own an AR15 and have it in my possession! After 85 days of waiting I finally was able to pick up my RRA Elite Operator II from my FFL (I live in md and there is over a 100 day waiting period to get approved for a regulated firearm, this is due to the passing of a current bill banning most guns we have come to love). So I took it home and pumped 30 rounds through it, absolutely love it! Well I wouldn't be posting pictures of it if I didn't add something you guys might think is cool... what do you think ;) http://i1309.photobucket.com/albums/s636/mhemling33/Guns/IMG_0085_zps73f6ce10.jpg http://i1309.photobucket.com/albums/s636/mhemling33/Guns/IMG_0078_zps0aa26ed4.jpg http://i1309.photobucket.com/albums/s636/mhemling33/Guns/IMG_0081_zps51dd2145.jpg http://i1309.photobucket.com/albums/s636/mhemling33/Guns/IMG_0080_zpsfbad8ff2.jpg |

Just my own preference. Does it hold a zero well? |
| The reason for the bipod is because I am interested in testing the diode to see if it can withstand the forces from recoil. After I find a diode that can take the beating then I will begin to figure out what to put it in and how to mount it ;) consider this my beta test 1. |

What is the output power on the one in those pictures? How "visible" (is that the right word?) is blue compared to red & green in brighter daylight conditions? Any chance that you could post a picture or two of the laser in brighter daylight? |

IR starts at 700nm to 1mm which is also pretty much in that range and is why nightvision can see it. Green is around 510nm so will also be seen by nightvision but probably not by gen 3. Nice rifle! |
| The high power stuff is difficult at first its like learning a different language and because you do all of the by yourself really you will kill a lot of diodes, but if you can stick with it its not that hard. You need pretty good soldering skills, antistatic prevention is a must, also you need a decent understand of electronic circuitry. If you are thinking about trying it the first thing I recommend buying is safety glasses for whatever wavelength you are going to attempt to build. If you have any questions shoot me a PM I will be glad to help |

Im not the best person to ask I own a pvs14 and have read the nightvision section quite a bit but im still a novice in nightvision. That question will be kinda hard to answer because the 520nm is out of gen 3 range but it will see the 808nm. Gen 2 will see the 520 but not the 808 haha. |

^^^^ please listen to him I really don't want to be kicked off of here. Sorry guys it would require me to pay $XXX upfront to be a dealer here so don't hold your breath ;) Sorry I didn't know. Do you know of any alternative weapon lasers that have similar output? Or maybe you can make a guide on how to make one of these |

Well I wouldn't be posting pictures of it if I didn't add something you guys might think is cool... what do you think ;) <a href="http://s1309.photobucket.com/user/mhemling33/media/Guns/IMG_0085_zps73f6ce10.jpg.html" target="_blank">http://i1309.photobucket.com/albums/s636/mhemling33/Guns/IMG_0085_zps73f6ce10.jpg</a> <a href="http://s1309.photobucket.com/user/mhemling33/media/Guns/IMG_0078_zps0aa26ed4.jpg.html" target="_blank">http://i1309.photobucket.com/albums/s636/mhemling33/Guns/IMG_0078_zps0aa26ed4.jpg</a> <a href="http://s1309.photobucket.com/user/mhemling33/media/Guns/IMG_0081_zps51dd2145.jpg.html" target="_blank">http://i1309.photobucket.com/albums/s636/mhemling33/Guns/IMG_0081_zps51dd2145.jpg</a> <a href="http://s1309.photobucket.com/user/mhemling33/media/Guns/IMG_0080_zpsfbad8ff2.jpg.html" target="_blank">http://i1309.photobucket.com/albums/s636/mhemling33/Guns/IMG_0080_zpsfbad8ff2.jpg</a> Years ago i had a red laser on my squirrel gun for low light use towards dusk. The dispersion of the laser helped to illuminate a target down range, squirrels. Because of the differing lines of sight for the laser to my scope, i found the dot would climb my verticle reticle as range increased. I would know if i was 100 yards for where zero was matched to cross hairs or further based on how high the dot rose above the reticle. A peraon could probably conduct a series of tests to see where the dot met the reticle at various ranges and then compared to a known dope for shooting that setting, load would still need to be recorded at all distances for a second correction to bring bullet intersection to dialed range adjustment. I never got around to it because my laser wasnt powerful or visible enough, was before green lasers. I mainly used the dot to try to daze a squirrel and see if i could get him to chase the dot around like a cat before i blew him up. |

Hey guys I just wanted to show you my newest project.... 100mw green illuminator
I had a person ask about using one of my green lasers as one for fox hunting (I think thats what he said). Well the Issue with my green lasers is they weren't adjustable so I figured out a way to adjust the flood size and it seems to be working pretty good. I still have to figure out a pressure switch for it but i would like to here your guys input on what you think good and bad! 
These pictures were taken tonight and its raining so I had to hurry up. I am aiming at a tree line about 150-175 yards away. You can see the different sizes I can adjust to and the overall power of the laser. 
The laser is set up so that you cannot go to an extremely tight dot that way it is less dangerous (it's still dangerous though just less). |

Already tested for ir output and it was only around 4mw ;) this was an over spec 50mw module. The ones that are the worse with ir is the claimed 150-200mw ones. Thanks for looking out though most people are not aware that majority of green lasers are dpss. I was playing around with my direct green osram diode and it actually would make one heck of an illuminator and no ir worries at all. This is what they will all be using in a couple years.
This is the osram pl520 with different focuses

Would it be possible to make a flip-on type of lens filter, similar to the lens caps & neutral density filters on the PEQ-2, that would block the green and still allow the IR only output? Something like that would be great for a dual purpose laser for those with night vision devices. I do understand that it is grossly inefficient as you are blocking all that higher power green laser output to get that minimal IR output, but it does seem like something interesting to try. |

That is how I test for IR. I use what is called an IR pass filter.
You can get filters to block or pass specific wavelengths here is an example of what I mean. You can see that transmission starts to occur in the high 700nm wavelengths and then peaks at around 875nm then levels out, but it blocks almost everything before 700nm. 
you can see how a this one will actually allow red and IR to pass 
I am no expert in NV and don't own any device but what your saying makes alot of sense i would think it would work. |

As mentioned less than 1mw@850mn is plenty for a targeting laser with 3rd gen night vision. 780mn is still slightly visable and 930mn is wasting power as it is leaving the visable spectrum on night vision. Now if you could make an focusable ir illuminator like the green one above with an 100mw 850mn diode with a potentiometer to control the brightness it would be a hit. I don't think it would be legal to sell but a do it yourself thread could get a lot of attention. |

First time I've seen a visible laser that can be focused like a peq illuminator. Impressive! |

Thanks guys I appreciate the compliments!

what mount is that & where can I get one? The mount was off of a cheapo china laser sight that I had taken apart to play with ;) I don't know where you can grab on like it this was in my random parts bin and just happened to fit that flashlight nicely. The sticker on it I already had. |

Quoted: The reason for the bipod is because I am interested in testing the diode to see if it can withstand the forces from recoil. After I find a diode that can take the beating then I will begin to figure out what to put it in and how to mount it ;) consider this my beta test 1. Good job on the handhelds though.

If they are using the osram diode you can upgrade the driver to 200-300ma and get close to 100mw output ;) |
| I am new to all of this, but a green laser caught my eye last night in a gun shop and I researched it last night. The reviews I read basically said it was a POS because the beam spread out too wide at distance. Another comment was that it was limited to 5mW as all mountable lasers are required to be limited. Your post is very interesting, but is there some reg out there that limits lasers to 5mW? The laser I read up on was a Barska GLX that I just happened to see. I liked the price point, what is a good affordable laser? Apparently the GLX is not worth buying. |

I must be a little slow, but I'm going to need some translation on your response. Old truism, not just with gun parts, but with all products. The basic premise is that in an ideal world, a product can be: 1. Of high quality 2. Affordable 3. Available now Unfortunately, in the real world, you can almost never satisfy all three, you have to pick which two are most important to you: If you want high quality, and you want it now, you're going to need to pay the immediate asking price, which is most likely high. If you don't want to pay much money, you have to either wait for the high quality stuff to either a) come down in price, or b) be available used. Or, you could settle for cheap but low quality. I won't belabor it by going through all the permutations, but hopefully you're understanding the concept now - "Good, Cheap, Now - pick two." ~Augee |
