摘要
设计了一种半导体激光器驱动电路,论述了半导体激光器的构造及其电路原理,阐述了半导体激光器驱动电路中恒流电路与恒压电路的工作原理与设计思路。通过在电路设计中增加恒压电路模块,有效地降低了半导体激光器的功耗。
A driving circuit for a semiconductor laser is designed. The structure of the semiconductor laser and its circuit are presented. The operation principle and design ideas of the constant current and voltage circuits in the semiconductor laser driving circuit are described. The power consumption of the semiconductor laser is decreased effectively after a constant voltage circuit module is added in the design of the circuit.
