摘　　要：设计和研制了一台石英毛细管波导型H_2喇曼池,用450nm染料激光研究了H_2的受激振动喇曼散射,测定了一阶Stokes波输出能量与H_2气压之间的依赖关系。最高能量转换效率为20％。用Oxazine-1染料激光作泵浦源获得三阶Stokes信号,得到的红外喇曼散射最长波长达6.57μm。A quartz capillary waveguide type H2 Eaman cell has been designed and investigated. Stimulated vibrational Baman scattering in H2 was studied by a 450nm dye laser pumping source. The Stokes-1 wave output energy was measured as a function of H2 pressure. The maximum energy conversion efficiency was 20%. The Stokes-3 pulse waveform was obtained by oxazine-1 dye laser pumping source and the maximum infrared Eaman output wavelength up to 6.57μm was obtained.
