A diode side-pumped acousto-optic Q-switched Nd:YAP laser operating at 1.3414 microm has been reported. The stabilities of resonators and the influence of the temperature of cooling water on output power have been experimentally investigated. The average output powers and pulse widths with different couplers and repetition rates have also been measured and analyzed. Under the repetition rate of 5 kHz, a maximum average output power of 47.5 W was obtained with an optical-optical conversion efficiency of 8.6% and a slope efficiency of 20.2%. The peak power and the pulse width were 48.8 kW and 195 ns FWHM. The beam quality factors M(2) directed along the a and c axes were 22 and 28, respectively.
据报道，一台波长为1.3414微米的二极管侧面泵浦声光调Q Nd:YAP激光器已研制成功。通过实验研究了谐振腔的稳定性以及冷却水温度对输出功率的影响。同时，还测量并分析了不同耦合器和重复频率下的平均输出功率和脉冲宽度。在5kHz的重复频率下，获得了47.5W的最大平均输出功率，光光转换效率为8.6%，斜率效率为20.2%。峰值功率和脉冲宽度分别为48.8kW和195ns（半高宽）。沿a轴和c轴方向的光束质量因子M²分别为22和28。
