Abstract :
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°C 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°C-+35°C; and temperature control precision is 0.5°C.
