摘要

本文首次采用带内泵浦结构设计了一种高效双二极管抽运Tm:LGGG无序晶体激光器。在1500 ~ 2300 nm范围内对Tm:LGGG晶体的室温吸收和发射光谱特性进行了表征。在连续波状态下，最大输出功率为11.5 W，吸收泵浦功率的斜率效率为57.1%。在输出功率以上时，估计光束质量因子M2为1.9。在重复频率为1 kHz的声光调q模式下，脉冲能量为5.71 mJ，脉冲宽度为102 ns，峰值功率为55.98 kW。

High power and efficient continuous-wave and acousto-optically Q-switched Tm:LGGG disordered crystal laser under in-band dual-diode-pumping

In this paper, we present a high-efficiency dual-diode-pumped Tm:LGGG disordered crystal laser using in-band pumping architecture for the first time. The room-temperature absorption and emission spectral properties of the Tm:LGGG crystal were characterized across the spectral rang of 1500–2300 nm. A maximum output power of 11.5 W and a slope efficiency of 57.1% concerning absorbed pump power were achieved in continuous-wave regime. Moreover, the beam quality factor M2 was estimated to be 1.9 at above output power. In the acousto-optically Q-switching regime at a repetition rate of 1 kHz, a pulse energy of 5.71 mJ and a pulse width of 102 ns were achieved, resulting in a peak power of 55.98 kW.
