摘要
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1.34μm单脉冲能量12.00mJ和11.45mJ,在平平腔结构下,得到最短脉宽38ns。实验还对平平腔结构下1.08μm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20Hz最高可获得1.08μm单脉冲能量28.5mJ,脉宽27ns。
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 1.34μm 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 38 ns pulse width of 1.34μm was obtained with a repetition rate of 20 Hz under the flat-flat cavity.The output characteristic of 1.08μm was also experimentally researched and the largest single pulse energy of 28.5mJ and pulse duration of 27 ns was obtained at a repetition rate of 20 Hz under the same flat-flat cavity.
