Investigation of the characteristics of a pulsed $CF_4$-laser

A study was made of the characteristics of a pulsed $CF_4$-laser, optically pumped by a pulsed $CO_2$-laser whose frequency was stabilized by injecting a signal from a low-pressure cw $CO_2$-laser. The laser output energy was observed to saturate with increasing pump energy, the maximum value obtained being 0.1 J at an efficiency of up to 1%.
