The 980nm laser is infrared laser. The 980nm laser is invisible. You can see little laser dot of 808nm laser. But the 980nm laser is totally invisible.

But we can see the 980nm laser under the digital cameras.  The following video will show you how to see 980nm laser.

The 980nm laser module has four parts: power lines,modulation lines,laser module head and laser module PCB.

This 980nm laser module is 200mw and powered by 5V batteries, here we use 3 PCS AAA batteries which is 4.5V to power the 980nm laser module.
