List - Existing Visible Wavelength Laser Diodes

[rhd]

Where is this commonly available?

Thanks!

Ya... nowhere. I think that's a typo. *wups*

Darn, there goes my uv build!

Is the Osram450 E only because of the Nichia445 being C? Osram450's are available rather easily for $40-$90.

The Nichia UV LD is the third, less sought after, but equally cool, of their exotic wavelengths.

The Osram450 is E only because I haven't updated the thread in a while

EDIT: Updated

Ahh, okay, haha. Aye I wish I could get my hands on a few Nichia specialty diodes... but they're >$4000 each! I'll never really understand their pricing, you think they'd want to make a return on their investment instead of holding it away in a tower.

For what it is worth, I found this...

Source for nichia NCSU033B uv led?

"I have ordered two Nichia NCSU033B UV LEDs directly via Nichia's inquiries page at https://www.nichia.co.jp/en/contact/inquiries.html, via their branch in the Netherlands (where I currently live).

I paid 81 Euros per piece plus import VAT (19%, about 31 Euros)."

I assume this is a flashlight type led, but perhaps that method could be used for ordering laser diodes?

 

[Sigurthr]

We can order any Nichia LD we want any time we want. It costs about $4000 per diode, no matter the source.

The LED in question is a chip type LED designed for surface mount tech.
http://www.nichia.co.jp/specification/en/product/led/NCSU033B-E.pdf

It's around 350mW output at 365nm. You can get canned lensed 365nm LEDs from Mouser for about $25 each.

Maybe it is better to specify the 440-460nm and the 635-685nm range ?
The Nichia 445nm and the Osram 450nm are clearly two different diodes, 3.8mm vs 5.6mm, single/multimode. The red range have even more different diodes.

What do you mean? I don't quite follow.

I have modified the OP to basically show ranges for blues (around 445) and reds (from 635 and up).

The reality, is the KasEO blues can themselves span a range of about 440 to 458 at the very least.

+1 for doing all of this! Thanks for all the hard work!

Visible is usually like 380 to 700 (even though most people can sort of see stuff like 808).

I'm not concerned about anything above 700. As far as I'm concerned, about 380 to 700 is the purview of this thread.

 

[Sigurthr]

If I had my way "visible" spectrum would be 350nm - 850nm, hehe. I understand that most folks can't see a lot of that though so I never push the issue.

The difference is merely in one scheme a whole lot of folks feel deficient, and in the other a handful feel special. XD

Personally it takes 800mW of 405 for me to see a good beam so 375 is kinda pointless in my mind. But that's just personal preference

375 isn't about the beam, it is about fluorescence.

 

[jakeGT]

I Understand that but it's pointless for me when I already own 405

Unless 375 and 405 fluoresce different materials?

Rainbow is filling up. Wish we had something in the yellow range

A year late, and I found 573.5nm
Edit: I just ruined the thread.
