摘　　要：作者介绍了一种串联结构的激光二极管群驱动电源的设计,内容包括软启动、电压-电流转换、光功率采样及放大、软件设计等部分。电源内部软硬件相结合,采用单片机和FPGA技术共同实现数字化控制,使这种串联群结构激光二极管驱动电源的系统稳定性能得到增强,串联群激光二极管的输出通过光纤耦合器进行耦合,从而获得较大的功率输出。It was described that a laser driver which can drive a group of series-connected semiconductor laser in this paper,the system mainly consists of slowly startup,conversion of voltage to current,sample and magnify of light power,software design and so on.The driver was combined by hardware and software,which uses singlechip and FPGA together to realize digital control,and enhance stability of the whole system whose driver is owning group of series-connected semiconductor laser,leading to their output obtain more larger power through optical fibre coupler.
