At work we're building a cool little project. Sorry I can't say what its for, but I thought you guys might find the actual device interesting, so I posted some videos on youtube: Overview Cool Aberration Patterns Focusing Interference It generates some very interesting patterns. If anyone could...

Ah, well then for the moment I will try to set things up with green and look into buying one of those blue DPSS ones. I think I'll post a new thread about the project, maybe people will find it interesting :-).

Ah. That would explain it. I really had wanted a 5mW gaussian beam :sigh:. I guess I'll try cranking it up to 500mA ish and put a spatial filter on it

Actually, looking at your chart, I'd say 5mW @ 240mA is about right. The setup is current limited, so probably the full 5V is not getting through.

Thanks. I was afraid of that. Yeah, actually, it seems to overheat and produce a uniform dim blue light if I leave it on too long. It pulls about 240mA at 5 V. The beam does seem to be very close to the spec.ed 5mW, its brightness appears about the same as a 5mW DPSS 473nm that I had measured...

I recently bought a blue 447 nm 5mw laser pointer and was very surprised by the beam shape, I realize laser diodes are supposed to have a rectangular shape,but this seems extreme. I wondered if anyone could tell me if this is normal for this type of laser? All of my previous ones have been dpss...
