室温下ZnS干涉滤光片的快速开关

Fast switching of ZnS interference filters at room temperature

本文中以连续Ar^+激光作为维持光,以脉冲Nd:YAG倍频激光作为触发光,用CW+P的方法在室温下实现了ZnS干涉滤光片的快速开关。开启时间为300ns。在理论上分析了实现快速开关的条件。

Fast switching in the ZnS interference filter at room temperature with the method of CW + P are reported, The samples were excited with a CW Ar+ laser as the holding light and a pulsed Nd: YAG frequency-doubled laser beam as the exciting light. The switching time is 300 ns and the conditions for realizing fast switching are analysed theoretically.
