对准分子激光拉曼种子源进行了深入研究。采用波导型拉曼地增强拉曼转换，并在氢气中掺入一定比分的氦气来控制向各阶斯托克斯光的能量转换。当无掺杂时，获得一阶斯托克斯光的最大转换效率η＿（ｍａｘ）＝３７％。当在氢气中掺入氦气比分为５％时，在泵浦能量范围５０～８０ｍＪ内获得一阶高转换效率（η＇≥９５％η＿（ｍａｘ）），二阶及高阶斯托克斯光的转换受到抑制。对实验结果进行了理论分析。
Aligned molecular laser Raman seed source for further study. Raman conversion with waveguide-Raman enhancement and helium gas incorporation in hydrogen to control the energy conversion to Stokes’ light. When undoped, the maximum conversion efficiency of first order Stokes light η max = 37% is obtained. When the content of helium in hydrogen is 5%, the first order high conversion efficiency (η’≥95% η max) is obtained in the pump energy range of 50 ~ 80mJ. The second order and high order Stokes Light conversion is suppressed. The experimental results of a theoretical analysis.
