Laser

About laser
LASER is an acronym and stands for Light Amplification by Stimulated Emission Radiation. Atoms of a crystal or gas contained in the device are stimulated by focused light waves leading to their amplification and concentration, eventually being emitted in narrow, very intense beams.

Specific features:
 * Very small beam divergence
 * Extremely high radiance
 * Monochromatic short pulses
 * High power
