This brief bulletin has been prepared by LIA's Laser Safety Committee to educate new laser users on the concerns and issues related to laser safety.
Energy is amplified to extremely high intensity by an atomic process called stimulated emission.
The use of the word in this context, however, refers to an energy transfer. Energy moves from one location to another by conduction, convection, and radiation. The color of laser light is normally expressed in terms of the laser's wavelength. There are one billion nanometers in one meter. The optical spectrum.
