Default Mother of all red diodes

Hi forum,

I just finished mounting the mother of all red diodes. It is a custom-manufactured 635nm laser diode with an output power of perhaps 10 watts or more. Its lasing threshold is a whopping 4.5A, yet my power supply is only capable of 9. I'm sure it could handle at least 15. :-)

Imgur: The most awesome images on the Internet

Now the question I have for y'all is, what shall I build with it? Apart from a monochromatic room, that is!

Default Re: Mother of all red diodes

To run it in CW you need to actively cool that thing. Looks like it would take some custom optics too. The driver for it won't be cheap either. Looks like it has a large emitter. That is certainly something most people around here don't have.

Default Re: Mother of all red diodes

None of your pictures show anything you could take rough beam or divergence detail guesstimates from.

Does it actually emit a beam? I just see a very large dot on a wall in the room in the photo taken outdoors?
Either way it looks like custom optics would be needed as Paul has mentioned.

You could try making a lab style laser with it if you can get the beam and divergence under control and find a correct driver.

Must be an LED.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Useless troll fighting.

Appears to have a very large emitting bar. Hard to tell anything from the photos other than bright red light.

Could be from a bright 635nm spotlight LED or some such thing--who knows?

Maybe "grenadier" will fill in the blanks about it's origin and original use--maybe some specs.

Default Re: Mother of all red diodes

I would like more information on this diode. Any information is better than none.
