本文报道在有机溶液(CH3)2SO中,用宽带5314埃激光泵浦,得到强6296埃斯托克斯相干受激喇曼辐射的实验。在中等泵浦功率密度下,受激喇曼斯托克斯辐射前向波能量转换效率达38％,观察到了后向斯托克斯受激辐射,后向波强度是前向散射波强度的80％,测量了前向散射的增益为2.5×10-3厘米/兆瓦,测量了前向、后向散射光束的空间分布。论证了后向散射光束方向性的改善。This paper reports the experiment in which by using broadspeetrum 5314? laser beam as the pumping radiation, an intense 6296? stimulated Raman scattering stokes emission was achieved in the organic solution (CH3)2SO. With a intermediate power density, the efficiency of energy conversion to forward stimulated Raman scattering approached 38%. The backward Stokes stimulated emission was observed, and the backward wave intensity was about 80% of the forward scattering intensity. The gain of the forward scattering wave was measured and was about 2.5×10-3cm/ MW, the spatial distribution and the beam divergence of the forward and backward waves were measured. The improvement of the beam direction of the backward wave was demonstrated.
