摘　　要：简述了激光起爆机理,介绍了一种应用于弹载环境条件的光纤输出二极管泵浦激光器。比较了激光工作物质Nd∶YAG和Nd∶YVO4吸收泵浦光的情况。阐述了LD侧泵Nd∶YVO4浦荧光分布,及光纤耦合透镜设计。激光器光纤单脉冲输出能量177 mJ,脉冲宽度198μs。The mechanism of laser detonating is introduced.A LD pumped laser with fiber coupling output is demonstrated which can be used under the missile borne condition.The light absorption pumped by Nd ∶ YAG and Nd ∶YVO4 is compared.The fluorescence distribution of the Nd ∶ YVO4 side- pumped by LD and the design of the fiber coupling lens are illustrated.The output pulse energy from the fiber is 177mJ and the pulse width is 198μs.
