SRS的物理机制

本文首先根据实验事实提出并分析了SRS产生的条件和基本特征,接着分析了目前对SRS的两种主要理论处理方法,SRS对应于Stokcs光子简并度n_s》1,其前提条件在于泵浦光简并度n_p》1,从而才能使其具有受激特性,最后,根据泵浦光的阈值条件和SRS的受激特性,指出几种通常描述SRS的物理图象都未能很好地反映出这些特点,我们提出的改进图象,不仅克服了上述缺点,而且还把散射光强不能大于泵浦光强的事实也表示出来。

PHYSICAL MECHANISM OF SRS

In this paper we analysed first the condition anl basic character of produce SRS according t0 experimental result. Then we analysed present both theoretical ways of research SRS, the condition of produce SRS(the Stokes photons degeneracy n_》1)must be pump photons degeneracy n_p》1, so that it is endowed with excited property. Finally, we point out several physical pictures of SRS cannot all interpret these properties, a improvemental picture is suggested by we that not only had overcame shortcoming above but also the scatting light intensity can not big than pump light inteasity is described.
