532nm Modified and Portable Green DPSS PWM Laser at 50mW+ Power, Burning Tricks and Testing

Описание к видео 532nm Modified and Portable Green DPSS PWM Laser at 50mW+ Power, Burning Tricks and Testing

Very similar cheap laser module as the last video but I swapped out the battery for a much lower capacity cell at the same voltage, improving the function of the laser with far less waste heat.

I also installed a threaded focusing lens for better burning tricks. The topology of the driver circuit is relatively efficient and consistent of a NPN power transistor and dual operational amplifier as voltage references for achieving constant current and power dissipation of 4.5W.
