摘要
报道了连续激光二极管单端抽运Yb:GdCOB晶体的单频微片激光器,提出一种新的激光输出方式,利用紧凑三明治结构和超短腔设计实现单频激光的空间、光纤双端输出。当使用1 mm厚晶体,抽运功率为360 mW时,实现了40.9 mW的1083.2 nm连续激光输出,斜率效率为13.7%,光纤耦合输出功率为337 μW;当使用0.2 mm厚晶体,抽运功率为380 mW时,实现了4.5 mW的1078.2 nm稳定单频输出。
Abstract
The continuous-wave single-frequency single-end-pumped Yb:GdCOB crystal laser is designed and experimentally demonstrated. A novel output method is proposed to achieve the spatial and fiber output with compact sandwiched structure, and the single-frequency operation is realized in an ultrashort cavity. The maximum output power is 40.9 mW and the slope efficiency is 13.7% at 1083.2 nm with 360 mW incident power and a 1-mm-thick crystal, and the fiber output power is 337 μW. Meanwhile, the maximum single-frequency output power is 4.5 mW at 1078.2 nm with 380 mW incident power and a 0.2-mm-thick crystal.
