摘要: 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LD阵 列紧密环绕棒状Nd3+：YLF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，1054nm波长处的自由振荡脉冲能量输出最大达1.01J，激光器的效率有显著提高。Abstract: This paper describes 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 are obtained by this way. Maximal output at wavelength 1054nm is 1.01J, converting efficiency form light to light efficiency is more than 60%.
