HELP :) We Need Big Red...

[steve-o]

I'd like to experiment with one of the 400mW 635's but I'm sure that the price is way out of range, not to mention (if this is a reliable product) MTTF... heh...

The outputpower will be nice, but I don´t think that you can get better output beam than the chinese Diode Lasers, becouse Emitter is ~100-150µm.

Not really.

Most of the 635 diodes I have seen have a beam spot of around 6x2mm. stack 3 of these side by side, and you have a 6x6mm beam.

The Optnext diode looks quite nice. I thought it was quite a bit cheaper tho?

Yes, the Broadband emitter lasers have a beam of 6*2mm, but this beam will be after ~5meters. At the output you have 6*6mm, or is it only MUCH Corona what will be also messured for the maximum power? I Think not...

Yes, the Diodes are nice, but upon now I haven´t found any better dealer with better prices ! :-(

Greetings,
Phil

I don't know what I'm saying...
How about taking a look at this?

And the price of that lil' beauty?

I have a 3W 633nm diode laser system here. Output is a 600um fiber bundle. I kludged together a fiber collimator from stuff in the lab and got a beam about 1" diameter with maybe 5-10mrad divergence. I'm sure that with proper optics, it can do much better. It's based on an SDL-7460-P6 diode module - same as Casey Stack's Big Red system. If you're still looking for a solution, let me know and I'll give you a call.

One other thing to conside is a dye laser. I've been messing with a Laserscope 630 dye head which makes about 10W @ 630nm in a stunningly small, tight beam. Big drawback is that you have to pump it with about 30W of green.

Damn man you have too much timeon your hands...

Yeah, please contact me ASAP RE: yer diode sys, there - I have a back-up plan in motion with just that - a LS dye-head - but it sounds like you have the HP-upgraded version of the 630 - LET'S CHAT ASAP!!!

Thanks, PM-ing you shortly...

same as Casey Stack's Big Red system

I remember that thread/pics. It was very impressive. How many diodes and what wavelength was that again?

[UV99LASER]

I have 7 plus watts of stable 630nm power and gaining.
It is a dye module pumped with a Laserscope ktp laser.
The beam is tight enough to fit on a pair of Cambridge scanners.

You can see it in action under the name fourth of July lasers here.

Hey Skipp, you only got 9 seconds of video and I did not see any red in those 9 seconds.
