Holy @#$%... $100 488nm diode!!






The 7675 is the one I keep mentioning to people to buy over the M462. Forget about the extra output of the M if you really want to see a lighter blue at half the cost of the 07.


Edit:
Watching that video it looks almost like my greenest 07 except that the 488 looks just a bit lighter in color. That's on my netbook. Watching it on my note 4 it looks greener and darker and closer to what I have.
I am NOT saying that mine is 488nm at all. It does look like the video one though. My bet is in person it is WAY more green than the video shows. What a shock it would be if they looked the same in person but I'm saying no way would mine be that high. It would have to be a super freak.
I do have difraction gratings now in different flavors and couldn't believe my 44 doesn't just burn it up.
Special thanks to Mattronium for helping me out with some I didn't already buy. My favorite thing is when we can trust each other and send stuff to share. Seriously. I have given away a ton of stuff and when I first joined I couldn't bear getting anything in return or someone just sending me something and even though it's not fair to not let someone else give back or be nice it took a long time to get used to it or at least not feel bad when someone else helped me out. Yeah that may sound strange to some but I can't help it. I'm a giver and I get joy/happy from doing something for someone else without expecting anything in return. It's who I am and it's not going to change. I keep trying to find ways to contribute to the forum in other ways too. I have some ideas but I have to see if anyone else has already done it.
I was thinking depending upon the real output of these I would build one into a pen to go with my pen collection although I sure wish I had another laser66/leadlight.

They did not get released today. Got this though.


-----------------
I have received your information and it has been forwarded for Urgent processing. Generally US Customs can take 1-2 business days to provide us the clearance. Also, if your shipment requires an FDA or any other government agency review, that process can take 3-5 business days to complete. I will continue to monitor for any updates and I will contact you again by 09/30 by 5pm your local time. If you have any questions or concerns regarding your shipment, please email or call me. If I am not available, please press 0 and any of my colleagues in the imports department can assist you. Have a wonderful day!

Maybe if driving hard pushes these up in the 490nm range it can get close to that awesome 500nm color. I am still kicking myself for letting that one go. Sent it out to get spectroed and it never came home. I had planned to do a nice build review with it get a lot of pictures but this is all I have now.:(

I had suspected at the time it might have been a PLT5-488 that got mixed in with a batch of PLTB450B as I never found anything like it before or again. I really don't think it was a fluke diode just a misshipment.

Mmmmmmm those pics are making me, eherm....you know :p I can't wait to get my hands on one of these bad boys. That's too bad about that diode you never got back, did you file a claim for it?

I have thought many times about a 500nm, that aquamarine glowing rod would look good, funny I used to hate those old aquamarine sears trucks, kind of a blueish teal, but as a laser beam it would be unique.

I would also love to have about 50 watts of 650nm in a 5mm wide beam, I still love that perfect red too.
 
Yeah, can't wait to do my own comparisons Red. Red can look really really nice especially the 650/660nm range as it is really red and not orange/red. Anyone want to see some beautiful red like Red and I are talking about take a look at the reds I posted in this thread:
http://laserpointerforums.com/f50/got-red-98344.html
So what exactly does that mean J? I'm assuming you have had that happen also? Regardless I don't want anything to make you frustrated enough to think about not selling diodes anymore. We used to do things like have a bunch of members contribute to a diode test in case anything went wrong so we would all take the load. I don't know what happened to things like that. It's a shame that isn't the norm anymore. We use to work together a lot more than we do now:(
 
Some awesome teaser pics Jordan, such a beautiful wavelength!
I'm keeping my fingers crossed for this deal to be a success. I've got a lonely J/L Ti-B waiting to be fulfilled. ;)
 
You really want to try over driving something that expensive and that you can possibly never get again? Wow. Assuming this is legit and they're of decent quality of course. I wonder if their multi mode 'oops' diodes or something weird... I have heard that 488 diodes are pretty fragile compared to other GaN diodes.

I have 3 main hopes regarding this.
1-They're for real.
2-They're reliable, relatively durable and long lasting.
3-They can consistently be acquired, and they're not some engineering samples that were smuggled out of a lab or something. It's gonna suck if they can only sell a small amount of them and we all need to fight over them.
 
There you go. 6 to 7.5 Vf. Probably a boost driver. Don't know how much more than 100 mA you want to drive it, though.

vf looks pretty high at 6v typical 7.5v max from the datasheet so hopefully a good source of boost drivers pop up as that doesn't seem to leave much wiggle room with dual lipo/buck setups.

Keep in mind that is a preproduction datasheet posted a year ago for more of an advertisement to get contracts not the final production datasheet. I really doubt we would be getting any test or engineering samples specially for this pricing meaning there could be changes for the actual production model. This was something that really makes me very skeptical about these guys getting them through official channels as they could not provide the production datasheet which would come with any shipment from a authorized Osram dealer.

Anyway if these diodes are 488nm and they are this diode and not another diode looks to be case negative so the driver will need to be able to work with continuous negative side which some don't like most of Lazeerers drivers or isolate. It will also require keeping a case ground which is not a problem for most all builds we do but if you have another diode in a multi diode build that is case positive at least one of the two would need to be case isolated.
