采用三镜耦合腔结构，实现了激光二极管泵浦紧凑铒镱玻璃激光器的调q、峰值功率振荡。通过改变外腔长度，成功地选择了单轴和多轴振荡模式。我们获得了920 W的峰值输出功率和8.3µJ的脉冲能量，在多轴模式振荡和60 W的单轴模式振荡。单模振荡在1532 ~ 1542 nm范围内可步进调谐。当外腔长度为0.4 mm和1.5 mm时，泵浦功率从270 ns增加到150 ns，从50 ns增加到8 ns，脉冲宽度变化很大。
Q-switched, high peak power oscillation of a laser-diode pumped, compact Er,Yb:glass laser has been realized using a three mirror coupled-cavity configuration. Single-axial and multi-axial mode oscillation was successfully selected by changing of the external cavity length. We obtained a high peak output power of 920 W and a pulse energy of 8.3 µJ in multi-axial mode oscillation and 60 W in single-axial mode oscillation. The single mode oscillation was step-tunable from 1532 nm to 1542 nm. Pulse width was widely variable by increasing the pump power from 270 ns to 150 ns and from 50 ns to 8 ns for the external cavity lengths of 0.4 mm and 1.5 mm, respectively.
