Various types of laserswith examples

A laser is composed of an active laser medium, or gain medium, and a resonant optical cavity. The Laser gain medium transfers external energy into the laser beam. It is a material with controlled purity, size, concentration, and shape, which amplifies the beam by the process of stimulated emission. The laser gain medium, in general, is pumped, by an external energy source including a flash lamp, another laser source, electric gas discharge, exothermic chemical reactions etc. . The pump energy is absorbed by the laser medium, exciting some of its particles into high-energy state where these can interact with light both by absorbing photons or by emitting photons. Under certain conditions, as mentioned in earlier sections, the amount of stimulated emission due to light that passes exceeds the amount of absorption resulting in amplification. Thus the basic components of a laser are: Lasing material e.g. crystal, glass, gas, semiconductor, dye, etc. Pump source that adds energy to the lasing material, e.g. flash lamp, electrical current to cause electron collisions, radiation from a laser, chemical reactions etc. Optical cavity, which consists of reflectors, acts as the feedback mechanism for light amplification. In this section, we would like to discuss various types of lasers like, solid state lasers, semiconductor lasers, dye lasers, excimer lasers, gas lasers, gas dynamic lasers, chemical lasers, X-Ray lasers, Free Electron lasers etc. Our intention is to provide salient features of various systems, without going into intricate details. The reader is advised to go through the various references for details at the end of the section. Solid State lasers Gas lasers Free Electron lasers
