报道了基于TEC(半导体制冷器)温控的激光二极管(LD)侧面泵浦的脉冲Nd:YAP(掺钕铝酸钇)激光器, 采用BBO(β相偏硼酸钡晶体, β-BaB2O4)电光调Q, 腔内不加入任何偏振元件, 使用平平腔和平凹腔在重频20 Hz时分别得到了1.34 μm单脉冲能量12.00 mJ和11.45 mJ, 在平平腔结构下, 得到最短脉宽38 ns。实验还对平平腔结构下1.08 μm的输出特性进行了实验研究, 采用相同的平平直腔结构, 在重频20 Hz最高可获得1.08 μm单脉冲能量28.5 mJ, 脉宽27 ns。

In this paper, we present a diode side-pumped Nd:YAP laser based on TEC temperature controlling that can produce single pulse energy of 12.00 mJ and 11.45 mJ of 1.34 μm output under the flat-flat cavity and flat-concave cavityat at repetition rate of 20 Hz. A BBO crystal was used as E-O Q-switched crystal and there was no polarizer in the resonator. The 38ns pulse width of 1.34 μm was obtained with a repetition rate of 20 Hz under the flat-flat cavity. The output characteristic of 1.08 μm was also experimentally researched and the largest single pulse energy of 28.5 mJ and pulse duration of 27 ns was obtained at a repetition rate of 20 Hz under the same flat-flat cavity.
