The laser driver and receiver circuit for diode pumped solid state laser mini-rangefinder

本文讨论了小型二极管泵浦固体激光测距仪系统的电路组成,重点研究了二极管激光驱动电源的结构和组成、雪崩光电二极管及放大电路的结构。本文研究的激光驱动器,在采用2W激光二极管作为泵浦源时,可以输出脉冲宽度200μs-2ms,峰值电流2安的电流;雪崩光电二极管在195V偏压情况下,可以达到最佳接收效果。

We discussed the electronic circuit of the laser rangefinder, The structure of the laser diode driver and the Si - Avalanche Photodiode receiver circuit is mainly analyzed, As the pumping source of a 2W diode Laser, the output of the driver is 200μs - 2ms in pulse width and 2A in peak current. When the reverse bias voltage of the APD is 195V, the optimal receive has been reached.
