摘要
基于推导得的聚焦束泵浦的受激喇曼散射耦合方程组。从理论上讨论了聚焦对有吸收介质的SRS增长及转换效率的影响规律。建议采用B=L/Z_r和K=l/L作为泵浦束的聚焦参数。为使不同的实验结果可以比较、实验应给出该参数值。
Based on the deduced coupled equations of SES pumped by a focused beam, we discussed bhe influence of the beam focusing on the enhancement and conversion efficiency of SRS in an absorptive Raman medium. Two parameters: B=L/Zr, K=l/L are suggested as the focusing parameters. In order to compare the results obtained in different experiments, the values of B and K should be given in the papers.
