CF(4) laser oscillator-amplifier measurements: small signal gain and self-absorption
Abstract:
Some of the fundamental parameters associated with the CF(4) optically pumped laser were measured with the aid of an oscillator-amplifier arrangement. The small signal gain for the strongest P-branch line was determined for pure CF(4) and for CF(4) in the presence of He and CO buffer gases at different pressures. The self-absorption of the laser radiation by CF(4) was determined for various P-, Q-, and R-branch lines at several temperatures. The data were used to determine that the loss mechanism for the laser process is associated with hot-band absorption from the 1 nu(2) level.
