Smallest Laser Possible?

[jermonster]

I'm planning on modifying these watches that I have with several gadgets and one of things I want try out is putting a laser in it. I'm pretty sure its possible, what's the smallest I can expect? It doesn't need to be all that powerful either. Any suggestions?

There are laser pointer watches out there already.A cheapo weak red diode.Putting a dvd diode in there would be a challenge

You could buy the Shock-Your-Friend Laser Pointer from DealExtreme. The laser module in it is the smallest I've ever seen. Cylindrical 6.6mm x 15mm long. It is black plastic and hold into place by sandwiching between the two plastic caps of the body.
