You'd have a pretty big diode, but they go for pretty cheap. No way you'd get that to turn any other color than infrared, the crystals would melt!
Anyways, everybody here just get a 5mW 532nm laser and use it for astronomy if you need it, it's not bright enough to see other than directly behind. If you need a collimating laser, anything 1mW or under should be fine for that task.
I've had 280mW 532nm lasers pointed in the sky for at least 20 minutes and I live less than 2 miles from a major airport.
