It's a 532nm 500mW 0.1nm Narrow Linewidth laser . The laser head and laser power supply in one case. It support manual control and software control. When software control is selected, link USB data cable and select 'PC' working mode. Let's check it now.  

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.

There are two   green laser module  includes a cooling fan. One is dot module, the other is  line module. It’s the high power laser as a small laser module.  The green line laser beam is very obvious during the daytime. Let’s check it.

Both 532nm and 520nm wavelengths are green laser sources, and the 520nm laser is a bit grassy green. But the principle of illumination of the two lasers is completely different: 532nm is dpss, and the inside is illuminated by a laser crystal. 520nm is a semiconductor laser, and inside is a laser diode.
