Green lasers are one of the latest innovations in tactical sighting devices. Are they really better than red lasers, or is this just a case of laser envy?
This is by far the best informative article written on any subject I've ever read. Never before have I read that Green lasers start as IR. The brightness of green being supported with facts is astounding. Can a green be converted back to IR?

from what i've learned in the past about color perception. The human eye picks up red best during daytime, and blue best during night. this is why sirens are as such. tennis yellow can be picked up relatively well during both day and night, which is why there are some fire dept. vehicles painted this color.

The green laser sights work at a wavelength of 532nm. This is close to the peak luminous response of the human eye. Red laser sights operate at wavelengths in the 630-650nm range, where the response is hundreds of times less than for 532nm. The Crimson Trace red laser sight operates at 633nm and the eye's response is 300 times less than at 532nm.

That is entirely situational. For military use you don't want to draw fire from every AK in the province. Police might be working from cover or concealment but usually aren't hunkered down in a gillie suit in hostile territory so daylight visibility is probably a good trade off. For self defense, a clearly visible laser beam to the center of one's chest or sinus cavity is a tremendous deterrent, particularly if it's being projected from a shotgun.
The ideal laser would contain both a visible red laser and a green laser along with a fast reacting light sensor to switch between red in low light and green in daylight.

A potential problem with green lasers is the entire beam is visible...so can can also easily see where the laser is coming from. Might be an issue??? I don't shoot handguns so not sure if this would be a problem.
