532nm Weird Output. (Help?)

So I got my first green Laserpointer today. It was a rather cheap unit from Ebay, probably around 50-100mw. It has been working fine for the last hour or so, but now after leaving it to charge the raw output looks very weird. Not round and clean like before, but rather like in the attached pictures. My question is, does anyone know how to fix that?

Scince I'm rather new to this hobby and I don't know a lot about green lasers, I'll just put some of my assumptions here.

I do think that, since it's 532nm, my unit is a Dpss laser. Maybe the crystal broke due to heat while charging? Or maybe it got damaged due to me trying to wipe the front of it with a microfiber cloth?

The first picture is the unfocused output, the second one is with a lense. 20210413_193202.jpg

That's what it looks like to me. I think you bumped the OC out of alignment.

Hope by 'one hour' you did not mean an hour w/o any rest??
Sometimes When that happens we see some of the pump diode. Why not just buy another.. long ago they were $40 now more like $4. good luck
