摘要

报道了一种新型小体积的半导体激光端面抽运国产Dy∶YAG单晶的黄光激光器。根据Dy∶YAG激光晶体的特殊能级结构, 采用半导体激光抽运, 利用4F9/2→6H13/2的能级跃迁, 室温下直接获得582.7 nm的黄光激光。抽运源采用蓝光LD, 通过温控系统调节LD的工作温度, 优化中心波长至447.3 nm, 从而实现抽运光波长与Dy∶YAG晶体吸收谱线的较好匹配。在吸收抽运功率为1.4 W的条件下, 输出黄光激光的平均功率为56 mW, 最大单脉冲能量达到1.1 mJ, 对应的光光转化效率为4%, 斜率效率为5%。

Abstract

A new miniature diode-end-pumped Dy∶YAG yellow laser based on the domestic single crystal is reported. According to the special energy structure of Dy∶YAG laser crystal, the yellow laser of 582.7 nm on the 4F9/2→6H13/2 transition is obtained using laser diode pump at room temperature. In order to matching the pump wavelength with the Dy∶YAG crystal absorption peak, the blue LD is used as the pumping source, and the center wavelength is optimized at 447.3 nm by tuning the LD operative temperature. With a total incident pump power of 1.4 W, the yellow laser maximum output power of 56 mW is achieved. The maximum single pulse energy is up to 1.1 mJ. The optical-to-optical conversion efficiency is 4% and the slope efficiency is 5%.
