Gas laser

Gas laser

A gas laser is a laser in which an electric current is discharged through a gas to produce light. The first gas laser, the Helium-neon, was co-invented by Iranian physicist Ali Javan and American physicist William R. Bennett, Jr. in 1960.

Advantages

* High volume of active material
* Active material is relatively inexpensive
* Almost impossible to damage the active material
* Heat can be removed quickly from the cavity

Types of gas laser

* Helium-neon laser
* Nitrogen laser
* Carbon dioxide laser
* Ion laser
* Gas dynamic laser
