Abstract
By solving the density matrix equations of a quantum system, the output pow er intensity of pulsed optically pumped NH3 and CH3OH far-infrared laser (O PFIRL) was calculated respectively by means of iteration method. Based on t he calculations, the spectral characteristics of pulsed NH3-OPFIRL and CH3O H-OPFIRL were studied and compared theoretically. The differences of spectr al characteristics between the NH3-OPFIRL and CH3OH-OPFIRL were found. Expe rimentally, a series of FIR emissions of NH3 and CH3OH cavity lasers pumped by TEA-CO2 laser were measured, and the experimental results were in agree ment with theoretical calculations.
