Laser electrical schematic diagram

The laser flashlight is cheap and good in quality, and has a high cost performance. Its main feature is its excellent focusing performance, with a range of 1200m~1500m. The naked eye observation shows that the light spot hundreds of meters away is still very small, so it is widely used in teaching, tour guides, and entertainment. Through test, it can be used for remote protection and remote transmission of data. The schematic diagram of the laser torch is shown in the figure. The devices are all patch elements, so the volume is very small. However, because of the high laser power, it is not allowed to directly shoot at the human eye.
