本发明讲的是激光电源装置,特别是介绍固体激光等的激活介质泵浦而用的闪光灯脉冲电源装置。这种电源装置的一般原理是把电容器充电,然后通过闪光灯使该充电电压瞬间放电。图1就是这种电源装置的一个例子。也就是说在端子10a,10b之间外加交流电压时通过扼流圈11,变压器12的初级就有恒电流流通,次级被感应成1000～5000伏较高的电压,它通过闸流管13a,13b进行全波
The present invention relates to a laser power supply device, and in particular to a flash pulse power supply device for pumping active medium such as a solid-state laser. The general principle of such a power supply unit is to charge the capacitor and then discharge the charging voltage instantaneously through the flash. Figure 1 is an example of such a power supply unit. That is to say, when the AC voltage is applied between the terminals 10a and 10b through the choke coil 11, the primary side of the transformer 12 has a constant current and the secondary side is induced to a high voltage of 1000-5000 volts. The secondary side of the transformer 12 passes through the thyristors 13a, 13b for full wave
