摘要/Abstract

摘要： 为提高激光泵浦源系统的整体效率,设计了一种负载自适应半导体激光器恒流驱动器。该驱动器能根据激光器阵列串联负载数量和驱动电流的变化,自适应地调节负载的供电电压,从而优化工作效率。实验结果表明,驱动器的最大输出电压为22V,最大输出电流为1200 mA,在驱动8个串联激光器负载的工况下,效率可达91.6%以上。这种负载自适应技术为设计高效的半导体激光器驱动器提供了新思路。

Abstract: In order to enhance the overall efficiency of the laser pump source system, a design for a load- adaptive semiconductor laser array constant current driver is presented. This driver can adaptively adjust the supply voltage of the load based on the number of series loads in the laser array and the changes in the drive current, thereby optimizing work efficiency. The maximum output voltage of the driver is 22 V, and the maximum output current is 1 200 mA. When driving eight series loads of the laser array, the efficiency can exceed 91. 6%. This load-adaptive technology provides a new approach for designing efficient semiconductor laser drivers.

Key words: semiconductor laser, load adaptive, constant current driver, soft-start protection
