CO₂スラブ型レーザーの small signal gain 空間分布

抄録

Spatial distributions of a small signal gain in a CO₂ slab laser have been measured by two dimensional infrared camera. The small signal gain has its peak value in the center of the laser medium between two electrodes and decreases in the vicinity of electrodes because of ion sheath and wall de-excitation by diffusing upper level CO₂ molecule.
