摘要：

Stimulated rotational Raman scattering (SRRS) at multiwavelength pumped by TEA CO2 laser was demonstrated in this paper. Raman mediums were cooled by liquid-N-2 and a multiple-pass cell (MPC) with 25 passes was designed and used. When the para-H2 was pumped by single-longitudinal-mode (SLM) circular polarized TEA CO2 laser on 10P(20), 9P(20), and 10R(20), 50 mJ 16.95 mu m, 350 mJ 14.44 mu m, and 536 mJ 16.9 mu m radiations were obtained, corresponding to energy conversion efficiency of 1.2, 11.7, and 13.4%, respectively. When the ortho-D-2 was pumped by CO2 laser on 10R(18), 108 mJ 12.57 mu m Raman laser was obtained with energy conversion efficiency of 2.9%.
