Does that mean the beam won't be that bad after all and how will this compare to a 445nm diode.

Thanks for that info Grix,
what if you could have the 300mW 635nm 5.6mm diode for the same price? (with smaller quantities)

This manufacturer claims it's Medical quality. I don't know if it is, but it IS a SINGLE ELEMENT Emitter.

No, I think I would rather have the 170mW one. The 300mW does have a single emmitter, but it's extremely wide, which makes the beam multimode and have absolutely terrible divergence without expensive and large optics.

So you can't make a handheld laser of the 300mW one, and even if the diodes are the same price, the beam correction optics would cost even more and be a pain in the a** to install.

are you asking this to me or Grix?

@Grix
I wanted to upload the jpg of the 300mW 635nm diode but this site says it's too large (page size) and can't shrink it, (if it does you can't read it anyway :-)

what can I do to it to be able to attach it to this thread?

EDIT- I zipped the file. ... I wanted to make a self-extracting zip file,
but the site upload routine doesn't support .exe files... so I hope you all
can unzip it to see the specs.

Let me know if it's good for you all.

Upload the pic to imageshack and as you do that, resize to 800x600.
Then use the "direct link" you get to put the pic here.;)

if it's resized to smaller, you can't read the text ..

I just zipped it, edited the last post and placed it on there.

XP and maybe the windows7 has zip built-in to the OS and unzips the file.

or, you can get the demo of RAR or UnZIP to unarchive it.

EDITED--- I also created the ImageShack link ... see 2 posts forward here .. :)

Am I reading this wrong, or is the beam divergence, in fact, absolutely horrible,
much worse than even the 445nm diodes?
Then again, that divergence is of the raw output from the diode, I wonder how well
it could be collimated with your typical o-like or aixiz lens...

I'm guessing you're looking at the datasheet Grix gave the link to?

EDITED

OK here's the ImageShack link, it did leave it at full size, with the zoom option on the page ... amazing :D

635nm 300mW TO18 5.6mm SPECIFICATIONS ... use the zoom function there to see the full sized picture

That is the divergence of the raw diode, but nonetheless, even with a lense it will still be worse than the 445nm's.

As I have said, the 300mW have horrible divergence without expensive optics and I would rather have the 170mW.

What divergence #'s are you looking for?

... and aren't those very fancy types (if exists) into 1,000's of Euros or USD$'s
 
My dream diode would be a 610nm SM 5.6mm .5W. I'd also like one that can do 5 to 10mW for everyday use.

For the purpose of this topic, I want a SM 635nm that will do more than 10mW.

Preferably a round beam with <1mrad, such as single mode diodes.

Any Laser specs I saw with <1nrad divergence were in the thousands $$$$
unless this was for a complete laser, and not just the diode ...?

was the ode2_071_hl63133dg_Rev1.PDF one of these diodes <1mrad ?

show me a datasheet or text file, with the specs of diode you want, and ...

I can ask the manufacturer if they have any like it,
if they do, maybe more here want them as well.

If I can get a better price on getting the better spec diode, it's better for
everyone ... you'll all have a diode better than anything you've had,
for making quality Holograms, or other scientific play :)
not just shining on a wall or burning stuff ... ! .. although that's fun too :D

I actually want you to be happy with the purchase, and want to also have
the best product to sell, at the best price.

I would want 650nm 1W+ in a 5.6mm package!
Click to expand...

I'll ask, ya never know, ... this was what's listed in the data they sent me.
Maybe it's been updated since, 'cause they recently said they have
an additional IR Diode that previously wasn't on the list, either, ... 914nm ... so ..

650nm 150mW SM LD TO18(5.6mm)
650nm 500mW MM LD C-mount
650nm 500mW MM LD TO3
650nm 1W MM LD TO3
650nm 1W MM LD C-mount


(who says they can't, 445nm 1000mW comes in 5.6mm) :)
 
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?

Anyway -
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:

I also asked if they have or will make a 635nm 1 watt in 5.6mm ...
they said no, and may also stop all 5.6mm parts in the future,
so if you like this diode, plan to get as many as you can afford,
when the purchase starts. ;)
