Abstract

For high power lasers there is a general tendency presently to explore the potential of gas lasers. Gas lasers have potential advantages over solid state laser materials. One can achieve larger geometrical dimensions and the active material can easily and cheaply be replaced if necessary. In addition, scattering losses will normally he lower and the breakdown field strength can be higher than for instance in glass lasers. Diffraction limited beam quality is obtained without problems and high repetition rates are possible. On the other hand there are two kinds of limitations peculiar to gas lasers: Firstly the cross section for stimulated emission G is comparatively large due to the small emission line widths ∆v of gases. This causes limitations to the storage of energy due to superradiance and parasitic oscillations unless the line can be broadened by suitable means. The second disadvantage is collisional quenching which is usually quite efficient especially at higher pressures in gas laser operating on vibrational excitation.
