(b) This schematic drawing illustrates how light from the flash lamp excites the Cr 3 + ions to a short-lived excited state, which is followed by decay to a longer-lived excited state that is responsible for the stimulated in-phase emission of light by the laser.

Laser is a type of light source which has the unique characteristics of directionality, brightness, and monochromaticity. The goal of this module is to explain how a laser operates (stimulated or spontaneous emission), describe important components, and give some examples of types of lasers and their applications.

Gain mediums can be solid, liquid, or gas, with examples like ruby in solid-state lasers and noble gases in gas lasers. Liquid dye lasers are noted for their tunability. The pump source excites the medium, while the optical cavity enhances amplification.
