you said it isn't IR , how did you determine that? also what model or where did you get this from? but it does sound like the crystals are out of alignment.

I tried turning it on and looked at it with a camera I already know sees IR. It's from amazon and its called Million Accesories Military Adjustable Focus Green Laser Pointer Pen <5mw 532nm Beam Powerful 5 Miles. I really hope the crystals aren't the problem cause I heard that cant be fixed, and what are "the crystals?"

Here's how the green lasers work. You can see where the crystals are in the diagram (KTP and Nd:YVO4):

If your laser isn't showing anything, including IR, maybe there's a busted connection inside the host. The host for your laser appears to have a rear clicky switch. Maybe see if you can manually make the connection at the rear using a wire or something. Make sure the laser is aimed away from your eyes in case it lights up.

If that doesn't work, maybe the board got damaged from the shock of being dropped. The battery might've rammed the module inside and broken it. You can try taking it apart and seeing what is inside and if it is repairable.

Maybe the lens inside got jammed or has some grit or something. You could try applying some extra pressure on the twist to see if it'll dislodge it. You might need to just open the thing up and see if anything is wrong.
