我们报告了直接二极管泵浦可调谐掺铬固态激光器的首次运行。小型紫翠玉 (Cr:BeAl2O4) 晶体由两个可见激光二极管纵向泵浦。使用 680.4 nm 处的 R1 谱线进行泵浦跃迁的阈值泵浦功率为 12 mW，斜率效率为 25%。测得的激光输出带宽为2.1 nm。
We report the first operation of a direct diode‐pumped tunable chromium‐doped solid‐state laser. A small alexandrite (Cr:BeAl2O4) crystal was longitudinally pumped by two visible laser diodes. The threshold pump power was 12 mW using the R1 line at 680.4 nm for the pump transition, and the slope efficiency was 25%. The measured laser output bandwidth was 2.1 nm.
