It’s 532nm fiber coupled laser system. It’s a output power tunable laser, 0~20W laser power can be adjusted by button. This laser has three working modes: CW, TTL modulation, Analog modulation. It coupled a SMA905 fiber, the coupling efficiency is about 80% at 400μm fiber. After turning on the laser, it need a few minutes for the laser to work stably. Let’s check it now.
