I've tried both. I didn't have much luck with the nonlasing laser diode. At 
low current, it wasn't very bright, and with just a little more current it 
lased and got way too bright. Either way, the beam did not spread very 
evenly. It may just be that I bought a substandard part, or that I mistreated 
it in some way.

LEDs have always treated me well. I simply sande off the front lens dow close 
to the wires, and they work like a champ, and it's easy to make a dimmer for 
testing coated mirrors.

Clear skies.
