505nm and 480nm diode RESULTS

Wow, that's a lot of money. If I had an extra, I'd ask no more than $75.00 for it now, and if a few more showed up probably no more than $50.00. A fair amount of profit is reasonable....IMO.
 





When I sold mine I only aimed to break even. I was happy just having them.

Granted, to a degree everything does have a price. I'd part with the 480 if it got me a 607, so around $2.5k
 
Not exactly. You aren't asking $2500.00 for your 480nm diode. Just a trade for a 607nm. When you sold those diodes I measured for you, didn't you sell the ones Billy has now?
 
I think it was only one... I think...

Z,Z,P,B,A,C,RIP,RIP, that leaves two I need to dig in my PMs for.

Edit: I may have sold one to him and traded the other for my 502nm host. So 2 I believe.

Now that said, I still have a spare diode myself, though thats insurance for the 480...

BUT for curiosity sake let's say !!!!!


It's funny how people don't take notice! I sold a complete custom with volt panel 477 for under $500. As if I would, this is fun reading though,
 
Here you see fluorescence in an iodine cell at 501.5nm. The light is comming from a laser diode with a free running wavelenght of 502.5nm. With feedback from a grating, the weavelengh cold be reduced to <1MHz and the laser is tunable from 505nm to 499nm (not optimized yet)

:crackup: That's a bit absurd. Like Paul said making a profit is absolutely fine but there's a limit before it becomes unreasonable. That's not the most attractive price Billy, just saying :whistle:

Has to pay for that big gold ring somehow. :whistle: :crackup:
 
@ Singlemode

That is very interesting. You got the line width down to <1 MHz at 501.5nm with diffraction grating tuning? I love everything about it. You only had to tune it down by 1nm to get this result? I know you've said that you have much more freedom of tuning this way, so was there a specific reason to keep it there rather than a different wavelength?

At 501,5nm is an iodine transition line and I had an iodine filled gas cell nearby. Hitting the line, enlightens the whole room :). I can tune my diode from 507.0nm to 498.0nm so far, with only a very simple setup (my test setup) and little optimization.

I am waiting for a new grating to reach the 497.0nm soon.

Oh, okay. So that glow is because of the iodine transition line you are introducing into the gas filled structure. That is quite bright. Can't wait to see your new setup with the new grating. I know you are interested in 497.0nm for something, but either can't remember what atomic transition is there or you never said.

Just got the brass TO-18 laser diode module that is a temporary module for testing laser diodes. It came with an AR coated 2 element lens in a brass lens housing. I chose 505nm to 550nm for AR coating as it is as close as I could get to the diodes we are seeing now. RA_Pierce also sent me the housings out of some 532nm pump diode's housings which can also be used for this purpose, but don't have a lens capability. They hold either TO-18 or TO-5. So, no more testing bare diodes.

I'm sorry, Joey. I meant the micro-printing around the diode's window. You should find one of these three numbers. You will have to use some sort of magnification to read it, but that will tell you which of these three diodes you have. And they are all different.

That linear driver that BowtieGuy linked me to is called the "Blitz Linear Driver" and is on Survival Laser's website.

Sorry for the lack of responses on all my posts, I'll be updating a few today. I just got in a few diodes that say "SB147E891" on the can. It doesn't seem like that matches the other ones you posted but I guess the sb147ec91 would be closest.
 
It's impossible to say where they would measure as that is a new number. Where did you get them? Just wondering as we might be seeing more of them.

These were from the same seller as the 488s, "Dora" from "dongguan laser". Maybe I'll have to send some to you again for testing if you are willing.
