Stokes efficiency是什么意思

这个所谓的斯脱克司效率是什么意思,哪位大哥能告诉我.先谢谢了


我是大四学生,翻译文章,在下面一段话中有这个东西,不知是何物

Repeated passes of the pump radiation through the crystal
increase not only the absorption efficiency but also the effective
pump power density. Therefore, the thin disc design is suitable
for quasi-three-level systems like Yb :YAG, which need high
pump power densities to overcome transparency threshold and
efficient cooling at the same time. Because of an additionally
high Stokes efficiency and good thermomechanical properties
of the laser host, Yb :YAG was chosen as presently the most
promising laser material to scale output power of the thin disc
laser up to the kilowatt range

这个Stokes Efficiency应该指的是Yb :YAG宿主粒子的荧光量子效率，因为它的泵浦波长为940nm，发射波长为1030nm，则理论量子效率可达940/1030=91.26%。

谢谢您,         
这下就明白了.

受教了，多谢
