In the paper,a low-cost drive and thermo control circuit of high-power laser diode are designed.The output of laser power is very stable,its stabilization can reach 0.01dBm.The paper focuses on the protection of the laser set also,it can avoid the damage of the LD from static over voltage and over current.The circuit has been used for half a year.It is very stable.
