3W @ 635nm

**QUAZAR** · 08-04-2007, 17:37

Found this diode array that outputs into a fiber tail. Any idea how easy or otherwise to collumate the beam into something usable? 3 watts of read sounds good to me. They also do a 5W 670nm version.

Damn... 5W of 670...

You need one of these, not sure it'll handle all that power though.

Hi

I have a 3 watt 660 fibre coupled , and got one of these
320142337303 on ebay for it. Auction ends in four hours ! Specs are on the Newport site.

Regards

How much did it go for?
Can you put collimating optics at the fibre end?

<edit> nevermind- I just saw the MG collimator. A bit pricey, that.
I'm still wondering how much the 3 watt 660s go for though...

I would like to know the emitter length and the fibre core diameter.

Fluff-
Are you going to have any more of these 3 Watt 660nm lasers for sale?

**Dr Laser** · 08-06-2007, 20:39

I actually have 2 collimators for this purpose. And from the picture I can see that even the end of fiber optic cable is the same.

**Photonbeam** · 08-07-2007, 17:24

If the fiber core is 50 microns or less you can get a good collimated beam about 5mm dia. and maybe 1.5mrad or less divergence.
