Multi-Raman effect and longitudinal-mode structure in optically pumped submillimeter wave laser

摘要

Based on semi-classical density matrix theory, multi-Raman interaction in multi-longitudinal-mode CO_2-9R (30) optically pumped NH_3 molecules laser was studied theoretically. With different parameters such as pumping power and operating gas pressure, the effect of multi-Raman interaction and the longitudinal-mode structure of submillimeter wave laser were also discussed.
