After the laser diode is fixed, the heating disk 5 heats the laser diode. As the temperature of the heating disk 5 increases, the heat conducting sheet 6 introduces the temperature of the heating disk 5 into the heating tank 7. Since the heating tank 7 is made of metal, as the heat conducting sheet 6 conducts the temperature, the temperature of the heating tank 7 gradually increases, and the bottom of the laser diode is heated by the heating disk 5, and the heating tank 7 heats the outside of the laser diode.

Compared with the traditional device, the heat conducting sheet 6 arranged in an annular shape makes the temperature of the heating tank 7 rise more evenly, and the heat is evenly distributed around the diode, which is convenient for the diode to be evenly heated. The temperature sensor 8 monitors the temperature of the heating tank 7, and the display 9 displays the temperature monitored by the temperature sensor 8, so as to adjust the temperature of the device according to needs. The control panel 17 is convenient for adjusting the temperature of the heating disk 5 according to needs to change the temperature of the heating tank 7.
