Design of High-power Diode Laser Driver under High-temperature Environment

摘要：

Diode laser driver’s performance directly affects the output stability and life of laser device. A design method of 100W high power fiber coupled diode laser module driver is described under 40℃ high-temperature environment in this paper, and its main contents include: constant-current source design, TEC double direction temperature controller, corresponding MCU controller and protection circuit design . The diode laser driver achieves the following functions: output current can be continuously adjusted from 0-45A; Current control accuracy is better than 2％; Range of temperature control is +15℃-+35℃; and temperature control precision is 0.5℃.
