Laser problem

[drummerdimitri]

Hello guys, I've recently started using my old green laser again, but the dot is always inconsistent. Sometimes it's a dot and sometimes it looks like a stellar cluster lol. Does anyone know what might be going on with my crazy laser? I must admit i've been f****** with it today. Made is work for like an hour non stop, inserted it in the freezer for 5 minutes to cool it down just for fun etc... do you think it will go back to normal with time or is it gonna stay that way? Thanks!

u gotta be kidding right?
i am not dmart at all at laser deals - but how do you think that fragile equipment would behave to extreme temperatures and more than 1000% duty cicle?
If there is anyone telling that you still have a good laser, i would like to see the magical idea to make it work!

Well it's a piece of crap anyway, so I really don't care if it dies...

I'm not an expert but it kinda sounds like your laser might be modehopping, not surprising after what you put it through :cryyy:

You can read more about it here in this thread if you're interested.

Remember that a trip through a freezer can cause condensation on the lens when you take it out. This isn't a new idea here and has been discussed before especially in reference to TEC cooling.
