Max output for a 635 nm laser, while affordable?

SO I was wondering if there are any 635 nm diodes that can give a significant amount of power (100+ mw) while still being moderately affordable? (under 1k) This is for a DIY build.

Thanks.
 





You can get some very high powered ~ 635 diodes with built in FAC from PLT but they are of course multi-mode / arrays rather than single diodes, so that beam quality will be less than best. I looked into single diode 635s a while back - nothing available more than about 20mw. So basically for 635 it is low power high beam quality or high power low beam quality but not both.
 
The old Pioneer DVR-S201 drives used a 635nm diode to write, but no one seems to know anything about it. Does anyone have any info about this diode?
 
Are you sure bout that Pioneer drive? Might be interesting to get...
 
Don't waste your $$ on high power 635. Rather go for a 300mw+ single mode 660. 635's are more like bright torches than lasers due do the horrible square beam. I'm sure those 635's with good beam quality are really expensive due to corrective optics.

I spent $700 for my 500mw 635. Worst decision. Should have bought, Two x 22x LG writes, PBS, Flexmod. Would have got a nice beam with 600mw power for the fraction of the price.
 
Anselm,

I have two of those drives, we use them for SACD authoring. I haven't ripped either of them apart though... Though yes I can verify that they are 635nm. I'm not sure at what power though. They're a little bit less than 1x in practice, even though I believe they were claimed to be "2x". They use a special authoring media, too.

Theres a 170mw 5.6mm that can be had for roughly $200 :)
Good beam specs apparently.
 
Hey aryntha,
as long as they are still useful to you with the authoring, it would be a shame to rip
them for the diode. But should one of them EVER stop working properly,
you know what to do, don't you?:eg:

blrock: you don't seem to know what you're talking about, 635nm is a much brighter
(lumens/mw) and more "orangy" red than 660nm DVD diodes.

Um... actually I can make a comment like this because I own a high power 635nm. If you read my post again I was saying how horrible the beam is of these multimode lasers. 2x660nm coupled may not be as bright but at least it looks more like a laser at a fraction of the price!

Yes 635 is brighter than 660...for the first few meters. After the 635 spreads out it appears dimmer than the tighter 660 beam. Compare a high wattage torch to a low power laser. If the 635 had a well collimated beam then there would be no comparison. But show me an affordable high power 635 with a narrow, collimated beam.

OK, sorry if I came across a little cocky. I guess I misunderstood your post, I appologize for making generalizing statements.
I only know about 635nm from my singlemode 20mW and 40mW diodes.
The 40mW is almost as bright as a 200mW LPC815...
