Abstract

A miniature superradiant NH3 optically pumped far-infrared laser (OPFIRL) with buffer gas N2 was theoretically studied. Base on the mechanism model of buffer gas, synthetical relaxation time was calculated. By solving the semi-classic density matrix equations, spectra of NH3 superradiant OPFIRL with buffer gas N2 was calculated, also the operating gas pressure. It was found that by adding buffer gas, FIR power could be raised, and there existed an optimum ratio of gases mixture and an optimum operating gas pressure which was higher than that of pure NH3 operating.
