help problem with laser after hardly any use

[paul666]

hi, im new here so forgive me if ive posted in wrong place..i have a 300mw 532nm class B green laser from a uk company , with moveable Colet around the on button that can be rotated so that the power button cannot be accidentally pressed. and a key is supplied to turn the laser in the off position when not in use
But after 60hrs use when i turn on all i get is a tiny small dot, you can't even see the line anymore..i have bought a new charger and 2 new batteries , and charged up for 10hrs , and still same, i also bought a NON chargeable battery and is same as well..im totally lost, can anyone help?

your laser is toast more than likely. Its probably a 301, 302, or 303 variant and if you use it consistent for more than a minute you over headed the ir diode and cooked it and no matter what batteries you put in it the thing will not work. And to answer a question before you ask it no you can not replace the diode in those very easy if it is not what i suspect it is then one of the better than I people will need to answer any other ?s you may have

Like Vortish said, it's likely a 301 or 303 laser. It looks like the laser is dead. Maybe because of overheating, or just because it's not of a good quality. I'm surprised you got 60 hours of use out of that thing. How long have you had it?
