Abstract :
By solving the semi-classical density matrix equations and developing a buffer gas mechanism model, the effects of buffer gas on the output power of optically pumped NH3 far-infrared cavity laser were calculated and verified by experiment. Our results showed that: the output power of NH3 far-infrared laser could be increased when a certain buffer gas was added into the laser medium, and there existed an optimum ratio of gas mixture and an optimum operating gas pressure which could make the output power of far-infrared laser reach a maximum
