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
