I would do the 5W inferred laser . being inferred it will bring the cost down and being 5W it will burn anything but you will need a seriose heat sink.
Hears a pic to help you.OK, I asked the manufacturer to clarify if the 300mW 635nm TO18 (5.6mm)
is single or multi emitter, and or single or multi mode
They confirmed it's a SINGLE EMITTER but not single mode.
The 30mW 635nm 5.6mm diode IS Single Mode.
can someone explain ?
I thought single emitter means it's a single mode diode, and
being it's multi-mode, but single emitter, is that good enough for you all?
it sure beats the specs for Beam Divergence of the other data sheets,
shown in this thread, for the other companies diodes ! :beer::na::yh:
You're really "grasping at straws" here.... Grix's is also multi-quantum wellHears a pic to help you.
The 300mW 635nm TO18 (5.6mm) diode in your spec sheet has a divergence of 35° x 7°. That will make a thin wide line, like this ________

The HL63133DG 170mW 635-642nm diode that Grix suggested, Has a divergence of 9° x 17°. Still a thin line but much more manageable.
Also with the diode Grix suggested, there will be more than just this laserist community interested in buying them
I understand.Dont get me wrong ill be buying a 300mW & some 30mW 635's. I was only trying to second Grix on the lower powerd diode, and that beter beam characteristics is usefull for a wider market than laser pointers.
I was not trying to say your not intelligent just trying to better clarify with my quick mspaint skils:tinfoil:
Isn't it also true, if someone wanted to use the laser for making a scanned hologram, they'd need a wide beam , such as this Single Element Multi-Mode Diode?... Some people do want a laser, for other than shining on a wall, and burning things.I voted for it because it was the best out of the ones in the poll. But I doubt I have any use for it when I can't collaminate it.
btw: Both diodes may be multimode but the 170mW is much better in terms of the beam. A 150mW also exists, and it's even better. Here are the collamination and divergence results:
ML520G72 diode properties
As you can see it can be used with a single lense, the 300mW can not.
IIRC, though I might be talking out of my ass here, for holography the best would beIsn't it also true, if someone wanted to use the laser for making a scanned hologram, they'd need a wide beam , such as this Single Element Multi-Mode Diode?
I'm just repeating what I heard from someone else... when they doIIRC, though I might be talking out of my ass here, for holography the best would be
single emitter single mode diode.
I was too lazy to check, but did you contact the projetor people over at the Photonlexicon about this as well?
They might be interested as well.
This is good to know, but what about now, and the quote with this manufacturer?Ball lenses won't work, you'll need lenses that corrects only one axis.
Also, I would PM Drlava if I were you. He has arranged lots of diode GB's, including the ones with the 150/170mW diodes I talked about. He can help you get connections in the world of diode manufacturers and good prices. If he can get a 150mW 635nm for 100 euros at just 50-100 quantity, who knows the price you'll get for several thousands! He can also channel this to photonlexicon easily.
He has an account on this forum:
Thank you Leodahsanwell, with 6mRAD divergence, at 1 meter away the dot would be 1.1cm. 10 meter away 5.6cm and so..
bad.. too bad.
