What is different about military grade beam laser pointer?

If the power of the laser increases, the danger distance increases by the square root of the power increase. From 5 mW to 500 mW lasers, the power increases 100 times -- but the danger distance increases only 10 times. (The square root of 100 is 10.) Both effects are good news for pilots and others concerned with increasing green laser pointer power. As consumers get more powerful lasers, the increase in danger distance (NOHD, visual interference) is smaller than one might expect. A laser 100 times more powerful is not 100 times more dangerous; Assuming the divergence is the same, it is "only" 10 times more dangerous. And because divergence generally increases with power, the beam may be even less dangerous due to increased diffusion. The human eye is most sensitive to green light at 555 nanometers. Compared to other colors from other equivalent lasers (for example, with the same power and divergence), this color looks brightest and is most likely to distract the pilot. Most consumer lasers emit green light at 532 nanometers. This is only 88% of the brightness of 555 nm light to the naked eye.
