Study on the spectrum of miniature optically pumped NH<inf>3</inf> submillimeter-wave laser

Abstract:

By means of an iteration method and taking into account the broadening of the infrared pumping laser, the spectrum of a miniature, optically pumped, superradiant NH3 submillimeter-wave(SMMW) gas laser pumped by CO 2-10R(8) has been calculated and studied by solving density matrix equations. Experimentally, the interferogram of miniature SMMW laser pumped by a TEA-CO2 laser with 10R(8) line is measured. This is the first time that the theoretical spectrum has been in good agreement with experimental results.
