The investigation of quality of active medium of FAF RF CO2 laser by luminescent method

The luminescent method was used to measure the spectrum of turbulent pulsations of gas density in fast- axial flow CO2 laser with radio-frequency discharge input. It is shown that gas density pulsations increase through gas discharge along gas flow axes. In continuous-wave fast-axial flow (FAF) CO2 laser there is subsidiary deterioration of quality of active medium due to intrinsic turbulence intensified by gas discharge energy input.
