This is 532nm 5W fiber coupled laser. It is a customized laser. Customized features is this laser system will output a low-power guide red laser before high-power green laser output. Add a modulation signal DC 0-5V, anlog modulation can adjust the 532nm laser’s output power. This test, we add 3.7V and we can get near 4000mW green laser. Turn on the AC power, first out is the weak red laser beam, after 6 seconds, the strong green laser beam come out. Let’s check it now.
