Standing-wave forward-backward gain asymmetry in optically pumped gas lasers
Journal Article

· Phys. Rev. Lett.; (United States)
A new type of forward-backward asymmetry is reported for the 119-..mu..m emission from a linear-cavity CH/sub 3/OH laser, near-resonantly pumped by a continuous-wave CO/sub 2/ laser. The observed asymmetry is related to a strong traveling-wave pump field and also saturating standing-wave--generated fields, a situation typical for most optically pumped linear-cavity gas lasers. A simple interpretation of the experimental results is given in terms of multiphoton processes involving one pump photon and several generated photons.
