大功率环形LD侧面泵浦Nd^(3+):YLF激光器的特性

Study on ring-LD side-pumping solid laser

研究了一种采用新型泵浦耦合方式的固体激光器。大功率环形 L D阵列紧密环绕棒状 Nd3+ :YL F增益介质进行直接泵浦 ,泵浦光的利用率和泵浦均匀性有较大提高 ,10 5 4 nm波长处的自由振荡脉冲能量输出最大达 1.0 1J,激光器的效率有显著提高。

This paper described a new method of pump-coupling. Ring-LD tightly surrounds YLF stick to accomplish directly coupled side-pumping, total pumping power is 3kW. Correspondingly ideal pumping light utilizing efficiency and pump-field distribution were obtained by this way. Maximal output at wavelength 1054nm is 1.01J, converting efficiency form light to light efficiency is more than 60%.
