摘要
测得了ＹＡＧ激光（波长为１．０６μｍ和０．５３μｍ．脉冲宽度为５０ｐｓ）作用下的透射式和反射式钠钾锑阴极具有稳定光电发射最大激光光强并对其进行了讨论．当光强继续增加一定值时，阴极薄膜将被蒸发。
In this Paper, the stability of the Na2KSb photocathode stricken by an ultra-short pulsed laser (the wavelength is 1. 06 μm and 0. 53 μm, and the width of a pulse is 50 ps) is studied. The maximal value of laser power density under which photocathode can work stably is determined and discussed.
