640 suggestions?

any suggestions how to build a 600mw 640nm module with a 3mm beam diameter?

do you have lots of money or not so much "lots of money" ???

the expesnsive way is a quad opnext 63133 with a pbs and waveplate and short fl lens

the not so expensive way is to wait and see what will come out of the whole mitsubishi mgldhudfu71 diode, where you will be able to do the trick with 1/3 of the cash and just two diodes

What divergence do you need? The opnext has the edge on beam quality over the mitsu '71 diodes. But, as LaNeK said, the price is much higher. I have been using a dual mitsu '71 in my projector for about 2 months and I can say, most wouldn't notice the slight difference in beam quality.

What are you using for blue?

what's a mgldhudfu71 diode?

[teknofon]

i want something that's single mode

[teknofon]

right now i have a sucky 445 from snoc that i'm going to add some prisms to

Then opnext diodes is what you want.

If you have a 445 multimode diode then what's the problem combining it with a multimode red? Just curious.

the thing with the 650 and 635nm multimode diodes is that if i want to keep the divergence down the beam is going to be to fat
to fit my dt40 wide scanners,

i rather have something that matches the green then the blue

and i'm used to the beam specs of my Ar/Kr

/.. and i'm used to the beam specs of my Ar/Kr

LOL .., ahem, .. I mean.. good luck with that.. (using LDs) .. Anyway, the Opnext HL63133DG 638 nm 170 mW or the HL6385DG 642 nm 150 mW are both single mode I believe. The preference from what I've read is the 63133 for good beam specs after collimation and correction optics. I believe they run somewhere between 100-160 usd ea, and are presently available for purchase.

life is hard when you have gotten used to gas lasers and have to use diodes


i rather pay 400 bucks for a 600mw beam that fits the mirrors
then 200 for a 600mw beam that is four times my mirror size

but how do i combine 4 Opnext HL63133DG?
can i knife edge them together like this ::
and get a 3x3mm beam?
or is my hopes to high?
