摘　　要：本文研究了不同泵浦光偏振态及氢气气压时,氢的振动及转动受激喇曼散射的竞争效应.在5atm的氢喇曼池中,以波长为532nm的椭偏激光为泵浦源,当椭圆的压缩系数为tg26°～tg32°时,获得了60多条Q(1)和S(1)混合谱线.并在低压氢及线偏或准线偏光泵浦条件下,观察到迄今尚未见报道的受激R(1)喇曼谱线.The competition effect for stimulated vibrational and rotational Raman scattering in H2 at various polarization of pump laser and pressure of H2 gas is investigated in this paper. With 5 atm of H2 gas Raman cell and 532 nm elliptically polarized lasor light, for which the compressibility of ellipse is between tg26° and tg32°, more than 60 stimulated Raman lines involving Q(l) and S (1) transitions are obtained. And under low pressure of H2 gas, SRS of R(1) transition pumped by a linear or nearly linear polarization beam, which has not been reported so far, is observed.
