１　引言　　文献［１，２］提出在固体激光器的抽运系统中应用具有干涉涂层反射器的前景。干涉反射器的特点是在整块石英组件或管子的表面形成干涉层，这种干涉层的高反射带光谱位置与激活介质的激励带相重合。这时，在高反射带外还有很宽的透过光谱区，保证抽运灯的非工作辐 1 Introduction The literature [1, 2] proposes the prospect of using an interference coated reflector in pumping systems for solid-state lasers. Interferometric reflectors feature the formation of an interference layer on the surface of a monolithic quartz component or tube. The high reflection band spectral position of this interference layer coincides with the excitation band of the activation medium. At this time, in the high reflection band there is a wide range of transmission through the spectrum to ensure that non-working radiation pumping light
