A gas dynamic laser (GDL) is a laser based on differences in relaxation velocities of molecular vibrational states. The lasing medium gas has such properties that an energetically lower vibrational state relaxes faster than a higher vibrational state, and so a population inversion is achieved in a particular time. It was invented by and Arthur Kantrowitz at in 1966. Pure gas dynamic lasers usually use a combustion chamber, supersonic expansion nozzle, and CO2, in a mixture with nitrogen or helium, as the laser medium.
