摘　　要：使用大功率 Ｎｄ： Ｙ Ａ Ｇ 激光器产生激光，通过光学玻璃窗和光纤把能量传到金属点火器中点燃点火药，从而达到在点火管内实现多点同时点火的作用．实验用激光成功的点燃了点火药．并且把激光单点点火，不同直径光纤多点激光点火实验结果与普通的电点火实验结果进行了比较，发现使用激光确实能实现多点同时点火，达到抑制膛内异常压力波的作用．The objective in this paper is to investigate the effect of different factors on laser ignition. By optic glass window and fibre, the laser energy generated by large power Nd:YAG laser is transmitted into different points, and multipoint uniform ignition is implemented. And the effects of single point ignition, multipoint ignition, fiber diameters and propellant on ignition processess are studied. On the other hand, the experimental results are compared with those of ordinary electric primers. It is indicated that the laser ignition can obtain uniform ignition and inhibit the abnormal pressure waves in guns.
