Abstract
Considering the broadening of infrared pumping laser, the spectrum of miniature optically pumped superradiant NH3 far-infrared laser pumped by CO2-10R(8) has been calculated by solving density matrix equations and using iteration method. It is first time that the theoretical spectrum has been in good agreement with experimental results.
