Default Help!

I were melting down some shrink tubing and my blue 1.6W 445 or 450nm Laserpointer has some weird frackles kinda looking like a carmourflage now. Does anybody know how to fix it or what I shall do now?

I have no idea what you are talking about. Perhaps a picture would help?

Edit: I moved your thread to Tutorials, Help & Repairs. Administrative announcements was not the correct place to post this.

I'll explain,
He was melting some tubing while shrinking and lazing with freckles and questions on camo.

Hope this helps.

Edit: I'll try to help after I know what's wrong with it. Picture Maybe?

Looks like your glass lens or diode window is dirty. Is that picture with or without a lens in?

Hm, probably what DTR said. or the diode lens might be cracked but I'm not sure. don't have a powerful laser yet.

Its just the diode.
As I said I was burning some plastic without anything that could have protected the diode. And if it is really just dirty how should I clean it?

Default Re: Help!

So you just held the uncovered diode up to some plastic to burn it? That is never a good idea, especially not with anything high power. The smoke and residue can get on the diode window (or lens if you have one on the laser), and at the high of powers it will almost immediately get burned onto the surface of the lens/window. You can try isopropyl alcohol+ a -tip, but theres no guarantee it will come off.
