摘　　要：本文描述了以新型高增益、低阈值、具有较大非线性光学系统的自倍频激光晶体NYAB为工作物质的小型激光器。泵浦系统是小型高效率开关型反激式脉冲泵浦源。文中讨论了小型NYAB脉冲激光器的结构、泵浦源设计、光泵光谱与自倍频激光晶体NYAB吸收谱的匹配以及为适应NYAB晶体的荧光寿命选择泵浦光的脉冲宽度等问题。A miniature laser system with self--frequency--doubling laser crystal NYAB as la-ser material, which has high gain, low threshold and considerable non--linear opti-cal coefficient, is described. The pumping source is a switch type and inverse exci-tation model in small size but it has high efficiency.The structure of laser system and the design of pumping system, especially the pro-blems of the matching between the emission spectrum of the pumping source and theabsorption spcctrum of NYAB crystal and the selection of the pulse duration ofpumping light to suit the fluorescence life time of NYAB crystal, were discussed,
