Optically Pumped Continuous Wave CF4 Laser

摘要

The Continuous Wave (CW) CF4 laser, which emits at 16 micrometers, wasinvestigated, and special attention was paid to the physical processes in this optically pumped gas laser. The experimental set up of the CO2 pump laser and the CH4 laser is described. The experimental study of the absorption of the combination band as a function of temperature and pressure is described. The gain anisotropy of the optically pumped CW CF4 laser is considered, and the directional dependence of the gain, and thus of the emitted power, is described. The experimental study of the CW CF4 laser as a function of pressure and temperature is described. Experiments with a resonance enhanced low pressure optoacoustic cell are described.
