With all the talk and inflation of the IR designators/lasers out there I was wondering why can't you take a high powered laser such as the OTAL and just change the diode with an IR one that they sell themselves or install a filter such as used by surefire on their lights.

not really familiar with either the OTAL or OTS IR laser diodes, but if the diode requires external lenses  then the visible light optics won't work.

BadSVT, I am pretty sure that LD will NOT sell an IR diode to anyone without the proper ID.

You guys need to spend some time with the search engine on EBay. Most of the IR diods are crap but a few are very, VERY, powerful and might just work. I have not done it myself but have looked into it deciding it was too much trouble as I already have an IR laser.

I did a quick search online and found severl companies offering IR diodes for reasonable prices, I just wonder if they will be compatible with an OTAL.

is there a schematic available?

We're men, we don't need schematics!

I have been doing some snooping around, and it looks like Laser Devices might even sell the components to you (or to two separate parties). They sell complete "ready to go" diodes in the 835nM (infrared) spectrum.  

Their web site even says "Find the solution to all your laser applications from building your own laser pointer to assembling a laser module for alignment purposes or testing. You can find it all right here. All parts are precision designed to give you the highest quality possible."

It is not illegal to own one of these or convert one, it is just "frowned upon" to sell them to non police /non government agenices (plain old civlians)....at least this is how I understand it.

I think all we need are some schematics....or some of you smarty pants out there that know all about laser wiring jobs.

Laser Devices Page with info

Now I just need to find a used OTAL  

Please let me know if any of you guys can get your hands on a schematic !!!

Why would you want to ruin the warranty on a perfectly good OTAL when their are other IR lasers available. Remember IR lasers also require expensive NV, without it they are worthless. Thats why I sold my AN/PAQ4C. I had zero places to shoot at night and did not see a reason to spend $5,000+ on NV to have it just sit in a safe.

My Newcon (thanks bob), and corsak, rest peacefully next to me in bed every night. I figure even gen1 would be less of a position give away then a flash lite, and an ir laser just makes you feel cool. I've got less than $600 in both, and if the lights don't come back on some night, then it will seem more worth while.

black gun,
that's pretty interesting ,what ldi's web page re: the diodes.
it seems that if one can find out what model #  or size diode assy. the otal utilizes.
you can replace it with a ir diode with the same size. it even tells you how long you should solder the leads for and temp. limits for the solder. so in theory it can be done. now trying to find an otal to experiment on is another question. wonder how much the diode assy. is selling for.

Why would you buy a used OTAL when you can get a good price on a new one!

You have a good "point" (pun intended )....I was just going to buy an "inexpensive" Gen I to play around with, and see if it was a cool set up or not.

Yes...this is the problem ....ah there is always a problem...and a kind of expensive one at that. I might try to find a less expesive laser to experiment with, but it sure would be neat to utilize the OTAL casing.

hey guys,

heres my $0.02

yes you can change out the diode, easiest and cheapest way to do it to find an old cd player, remove the diode and install in your laser for ir.
quick , easy and works.

Can you give us some more detail on this? Sounds cool...and I just happen to have an old CD player laying out in my garage.

Can you do any research to find out what IR diode is used in the OTAL IR? I am going to buy one, and perform the experment ....... I need a mad scientist laugh now......"ahhh ha ha ha ha ahhhh ha ha ha!!!"

blackgun,

all i know about the otal is that the visible diode is a 635nm and the ir diode is the 835nm.
it's kinda interesting what spectr has posted though......
this might be a cheaper way to go to experiment. with just a $20.00 laser,swap it out with a cd laser and see if it works with nvg's. still wonder how effective just the cd laser is.
i'm still interested to see what happens

That is what I was kind of thinking too....I will keep you guys updated on my work. I am going to buy one of the cheepo specials to start out my experiment with, and buy the OTAL in 2 months.
