摘要
设计了一种EFDA泵浦源半导体激光器的驱动电源,采用由PC机和单片机构成的上下位机的控制结构,具有恒定功率和恒定电流两种控制模式。该驱动电源具有激光器保护电路,电流精度和光功率控制精度分别为0.15%和0.2%。
A power supply for the semiconductor LD for EDFA pumping source is designed,which has an up and lower computer controlling structure consisted of PC and MCU. The power supply have the two modes of constant optical power and constant-current.Also the power supply provides protection circuit for the semi- conductor LD. The precision of current and optical power can achieve 0.15% and 0.2%,respectively.
