Default Re: red laser diode C-mount

500 mw? At 650 nm? 700 mw to 1 watt 638 nm would be my choice due to greater perceived brightness and easier package to mount the diode.



$20 http://www.ebay.com/itm/Oclaro-HL631...-/331181218015

638 nm red appears about 2X brighter at the same power.


1000 mw each, same ratio, of course.

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.

Default Re: red laser diode C-mount

I wonder how hard that diode can be pushed. It might make it to 1 watt. I think if I were trying to build a high power 650nm C mount build it would be a much higher power, though.

Default Re: red laser diode C-mount

Maybe, but that 638 nm Oclaro can and at a brighter WL for cheap. How much is that C-mount 650 nm?

Default Re: red laser diode C-mount

I bought my near 1000 mw 638 nm Oclaro pointer already built, don't know what driver was used in it but I bet if you contact DTR he has a driver which will work:

https://sites.google.com/site/dtrlpf/home/laser-drivers

Maybe another member can help with what they have used.

Edit: This page shows the driver he uses with that diode: https://sites.google.com/site/dtrlpf...w-638nm-diodes

HL63193MG Specs:



Some push to 1000 mw but is rated at 700. I've never had problems with mine at 940 mw out of the lens.

I wonder how much we can abuse this diode for higher than rated output? http://www.ebay.com/itm/USHIO-HL6328...-/262667453889

If you want 500 mw of 650 on a C-mount, here's one with a price: http://www.ebay.com/itm/650nm-500mW-...-/262355495958

650 is OK but 638 nm is very cherry! I'll never buy 650 if I can get as much or more power at 638 nm.
