Light Amplification (by) Stimulated Emission (of) Radiation

Many different types:

Ruby rod laser - basically a polished rod of aluminium oxide/chromium oxide (synthetic tuby), surrounded by apowerful flashtube. - Visible Red

Nitrogen laser, co2 laser (gas lasers) fairly efficient by laser standards, inivisble output but can be strong enough to cut metal

semiconductor - both invisible and red - cheap for low power

dpss - diode pumped solid state - these lasers use a "pump" diode which is usually 808nm, tis goes into a sliver of something called vanadate which take in light at 808bm (almost invisible Infra Red) and re-emit it at 1064nM (Invisible. It is then put through a crystal of KTP which halves the wavelength (doubling the frequency) and re-emits at 532nM - bright green

The laser grew out of the maser.
Micro waves and light waves.
Maser-Micro wave amplification [by] stimulated emission of radiation
The maser uses a resonance cavity ,The laser a solid state or gaseous lasing medium.
Laser - Light amplification [by] stimulated emission of radiation!

light amplification by simulated emmision of rays....well basically it is used to produce a coherent non dispercing beam of light by multiple refractions inside a highly polished glass cavity
