500 mw green??






There's no way it could be that cheap... my guess is a faked reading and a BR diode?

-Trevor
 
I sent the seller a message right after I noticed this, I asked him if he was going to have anymore in the future and who the manufacturer is, let's see what he's got to say.
 
It's an auction, I don't think the seller intends to sell it that cheap..
 
Also, did anyone else notice the title says "green" but it's a "blue" diode?
 
Optical power output (CW): 530mW
Operating current: 650mA
Maximum operating current: 700mA
Peak wavelength: 444nm

if that stuff is true i gotta have it:eek:
i didnt even know there where true blue diodes of that power 500mw of blue would be kickass!
 
Well, I got an...answer, I guess:

Dear laserlightgeek,

This is a very interesting product, may I ask who manufactured it and if you will have more in the future?

- ********




Dear **********,

To buy this device directly from the manufacturer it would cost more than $1000. There is only one manufacturer making a 450nm, 500mW blue laser diode. I have 20 now and can get more. I assure you it is very high quality not Chinese.

His pricing seems right, at least, if it's true. But, notice how he states "450nm" in the answer, but the listing clearly says "444nm".

Interesting indeed.

The pinouts are certainly bluray stylee. That cut off leg is a bit suspicious though. Wouldn't a diode from the manufacturer be intact? Even if it was harvested I would expect the legs to be of similar length.

450nm? Awfully close to a 405nm typo!

I've never harvested a bluray, but are the leads that long in a bluray drive? I thought they were trimmed down and nowhere near that long.

Also don't diodes shift their wavelength a little, maybe that is why it says peak wavelength, it shifts from 450 to 444. I think that could be possible seeing as how 635 diodes shift to 640.
 
Temperature shifts usually occur under extreme conditions, and a 6nm change is nearly an 18* temperature shift, not exactly common. While some diodes are naturally above or below their rated wavelength, I wouldn't count on that as the reason for the inconsistency.


Edit: Also, you're right, normally leads on harvested diodes are much shorter, those resemble the pins on 9mm diodes more than a harvested 5.6mm

Well, I asked the seller a leading question. I asked the noob question...

"Dear laserlightgeek,

Hi there,

Is this a diode from a bluray drive? I've been looking to build a bluray burner using the Kipkay flashlight hack. Will this one be okay from 2 AA batteries?

M"



The answer came back...

"No bluray is 405nm."

I might be willing to go in to see what these things are. Risky but maybe it's worth it.

He said that no Blu-ray is 405nm? I'm now more skeptical of this listing...

No reserve... I suspect as the auction progresses we'll understand why.
