Use of<unk> s in civilian and military applications is increasing
Military use -  range finders, target designators, guidance systems, non-lethal denial, and now being used as directed energy weapons
Civilian use -<unk>  cutter/engraver, precision measurement, pointers, welding, entertainment
Potential to cause<unk>  is largely dependent upon irradiance and beam wavelength
Irradiance
Amount of energy that hits the eye/skin per unit area
Dependent on output power, distance from source to target, and beam divergence
Human eye can focus<unk>  to a very small area on the retina increasing the irradiance by a factor of 100,000
