Abstract

In this paper, we demonstrated a diode-pumped acousto-optical cavity-dumped Tm:YAP laser for the first time. The pulses were coupled out of the lateral surface of the cavity when radio frequency signal was loaded on the acousto-optical modulator. A maximum output power of 1.28 W was obtained with pump power of 40.3 W at a repetition rate of 200 kHz, corresponding to a slope efficiency of 4.7%. The output pulse width of the cavity-dumped Tm:YAP laser was constant at 43 ns, and the wavelength was 1989.8 nm.

摘要

在本文中，我们首次展示了一种二极管泵浦声光腔倒空Tm:YAP激光器。当射频信号加载到声光调制器上时，脉冲从腔的侧面耦合输出。在泵浦功率为40.3 W、重复频率为200 kHz的情况下，获得了1.28 W的最大输出功率，对应的斜率效率为4.7%。腔倒空Tm:YAP激光器的输出脉冲宽度恒定为43 ns，波长为1989.8 nm。
