摘　　要：针对大功率激光二极管泵浦固体激光器(DPL)对大功率驱动电源的特殊要求,设计了一种大电流恒功率放电及驱动控制电路。将该电路与现有的充电和过流保护电路组成一套完整的激光二极管阵列驱动电源,并应用于基于大功率激光二极管阵列的DPL系统中。该驱动电源可为DPL系统提供频率为20Hz,脉冲宽度为230μs,200A以上的驱动电流,这将对多种以DPL为基础的激光武器系统产生重要的实际应用价值。According to the special requirements of high-power diode pumped laser （DPL） for high-power driving power, we put forward a particular discharge and driving control circuit based on large current and constant power. We designed a suit of laser diode （LD） array driving power supply by combining the existing charging circuit with the over-current protection circuit, and applied it to DPL system which was based on high-power LD array. Through electrical properties and relevant experiment, it is proved that this power can provide a more than 200A driving current with the pulse width of 230μs and the frequency of 20Hz for DPL. It has important value for kinds of DPL-based laser weapon systems in practice.
