摘要
把一台YAG激光器输出的激光分成两束,同时入射到布里渊散射池中,获得在不同条件下双光束抽运的受激布里渊散射的反射率随抽运能量的变化关系.实验结果显示,两束抽运光在产生受激布里渊散射过程中存在耦合并且相互增强.用四波混频过程对实验结果进行了讨论.
In the experiment,two laser beams splitting from a YAG laser beam are incident into a Bril- louin cell and the effect of the pumping energy on the reflectivity of stimulated Brillouin scattering is obtained. The experimental results show there exist coupling and enhancement between two laser beams, and this phenomena are discussed by a FWMF model.
