If military laser can form visible light, how much power is needed?

Military  laser color and the use of the environment, light is reflected in the air particles, close observation of light can be seen a large number of particles, the daily environmental air quality even under good circumstances will produce. But it is sensitive to green eye visibility, so as long as the green laser 532nm 100mW (0.1W) in the daytime can produce indoor clear light.military laser1

Military  laser can also have not visible, so a lot of the poor visibility, such as partial UV 405nm even 1W light power is not so obvious (even if the power can burn paper). Infrared laser welding of carbon dioxide, but also do not see the light 35W (can burn the carton)military laser2

These small military laser devices do not have a “buzzing” sound, the normal equipment of small power does not produce the current sound, if you’re curious can buy a large power laser pen; but please Caution!, this can see the visible light laser power can easily reach permanent the impact and damage the retinal aviation safety, must not be irradiated human or animal and spacecraft.military laser3

Lithography technology does not seem to be required in military laser. laser photon transitions of atomic / molecular release. The excimer laser and the ultraviolet light source, atoms, molecules have been excited into a plasma state, we don’t usually identified “excited state”, is from the outside level transitions to the ground state, said it is also not what laser, error.
