From what I understand eye damage is possible up close. Esclation of force begits esclation of force. Laser use would make it very tempting to increase the force of the dispersion tactics used by the police.

I'm guessing that in the US lasers are more associated with firearms than in Greece, due to a firearm ownership prevalency difference? Also, I think it is different in a demonstration situation than some cop patrolling alone and having a laser illumination. |

The laser pointers are a clever idea, but the execution leaves something to be desired. Anyone with a little persistence can purchase (or make) a laser pointer powerful enough to blind by itself, thereby eliminating the need for coordinated activity. Ideally one would use a laser in a non-visible wavelength so that the blinding would happen discretely and without risk of the laser wielder being located.
There is a simple countermeasure here; protective glasses. So in the grand scheme of things I don't see lasers being a disruptive technology. |

Me thinks your vocalizations are coming from your posterior but apologize in advance if mistaken. fisherman The US Army uses lasers in the IR wavelengths for aiming while using night vision equipment. It would be kind of stupid for our soldiers to run around using NV and essentially being invisible then turning on visible spectrum lasers that would show the enemy exactly where they are. (One of Murphy's laws of combat, "Tracers work both ways.") An ultra-violet laser would be invisible and do serious, nearly instantaneous damage to a person's eyes. Aiming would be accomplished the same way you aim a rifle, with sights. Only you wouldn't have to accommodate for bullet drop. |

Me thinks your vocalizations are coming from your posterior but apologize in advance if mistaken. fisherman My company makes IR lasers for measuring in industrial settings. The visible wavelengths of light are only one tiny portion of the electromagnetic spectrum. We are now making the move to visible lasers. Visible lasers reduce the danger classification of the laser because when it is invisible you have no indication to turn away from the light before damage to your eyes is done. Invisible light is everywhere. The best example of IR light is the heat you feel at a distance from a fire or hot object. An everyday example of UV light it the "black light" in a bar. You don't see it until it excites white things to give off visible light. Protecting for your eyes from laser light is rather simple but it does help to know the wavelength of the light you are trying to avoid to maximise protection. With the weak IR light (>5 mW) we use in our lasers any green glass or plastic will offer protection. However, to maximise protection special lenses are required. Normal clear glasses will protect your eye from weak UV. According to my eye doctor one of the advantages lifetime eyegrasses wearers have is a lower incidence of cataracts caused my exposure to UV light from the sun. |

It is a particulate so an N95 mask would keep most of it out of your lungs, which would leave your eyes just stinging a little bit. In an open area, it does even less. |

Cheap green laser pointers can be pretty dangerous because they aren't strictly 'green'. They use an 808nm (IR) diode to excite an Nd:YAG crystal which outputs 1064nm (even longer IR) which is then doubled to 532nm (green) in a KTP crystal. After that, a filter should stop the IR and let the green light pass through, but in some cheap lasers the filter is not installed. These then output several times as much invisible IR light as green light. 1064nm is a particularly nasty wavelength because it passes easily through the lens of the eye to burn the retina. Other wavelengths (like the 'eye-safe' 1500nm lasers) are stopped by the cornea where they cause cataracts, which can be repaired to some degree vs. burnt retina which is irrepairable. Laser pointers can be much more than a distraction. A rioter pointing one of these at a cop might as well poke him in the eye with a stick. Either action can cause permanent loss of vision. |
