摘　　要：报道了半导体抽运的Nd:YAG叠片热容激光器的理论与实验研究,并用热容激光器的理论模型计算了在一定的工作时间和介质温升内激光输出特性,用Zemax软件对其抽运结构进行了模拟计算。实验中采用的4片Nd:YAG晶体尺寸均为63.5mm×38.5mm×7mm,抽运平均功率约110W,重复频率为10Hz,占空比为0.2%,获得了最大19.1W的1064nm激光输出,光光效率约17.4%。最后对两种抽运结构的叠片激光器进行了比较,提出了下一步的改进方案。A diode-pumped solid state heat capacity disk laser is firstly fabricated with Nd：YAG slabs. The output characteristic is calculated by using the theoretical model of heat capacity laser, while the relations of the output power, the temperature and the time is obtained, and the pump light intensity distribution is calculated by the Zemax software. The four Nd：YAG slabs are 63.5 mm×38.5 min×7 mm in size. The average pump power is about 110 W, repetition rate is 10 Hz, and the duty cycle is 0.2%. The maximal output average power is 19.1 W, and optical-optical efficiency is 17.4%. Two disk lasers with different pumped configurations are compared, and next improving schemes are brought forward.
