When you say that it shorts out - what is actually happening?

- Is the laser just turning off?
- If so, does it work again later?

I feel your problem is that your Wall Wart needs to be at least
12VDC at 3 Amps to be able to supply the proper amount of
current...

Before the Wall Wart got hot.... did you get any kind of beam
out of your Laser....

Post a clear picture of the Label on the Wall Wart that you
said got hot...
