Nichia 460-470nm 9mm 1.4w?!

[NightExplorer96]

Maybe all you "laser-pros" can raise money and have someone test it like you did for other diodes?

Im subscribing, this could be interesting. If I ever have the money one day, might consider getting one.

Actually, pushing causes more than a slight wavelength increase. 3 to 5 nm would be a reasonable range if they behave like other blue multi modes.

It would be nice if these red shift a lot...although i cant imagine they do, else why would Nichia sell them as something different from the 476? At that point, you would have overdriven diode A being the same as normal or underdriven diode B- basically the same thing.

They would sell them separately because the goal is to not have to overdrive them.

They are supposed to last thousands of hours at spec current. Overdriving them just decreases that life dramatically.

I almost want to wait on RHD's findings ... but it's shipping from China ...

I guess I should be patient.

It will be hard, but I am holding out for his review and measurements. There are other things to buy in the meantime.

It won't be a review, it will be an "okay, diode arrived, here's the wavelength" post, and a screen capture of the chart.

Awesome, thanks for taking the dive RHD.

I have one coming as well and can do some power/efficiency testing on it. They did say they are not shipping till the 8th though. So it will probably be two weeks before we see them.

Shipping from China to you only takes a week??

The urge to buy is strong in this one...Hmmm...

 

[Jmillerdoc]

I gonna take the dive too. Can't let all you guys have the fun without me. I'm glad I lost my bid war on that recent 473 DPSS 150mW lab unit on eBay. This will be way better for the plans I have for it. Cheaper too. Great discovery! Deserves a good repping...

 

[Atomicrox]

Great news! Price isn't that bad considering the power and novelty.
Bet we can push these to 2W and get the WL a bit higher.

I'm seriously considering getting one.


On a somewhat related subject, searching for 470nm laser turns up some stuff:
Blau Laser Diode 470 300 MW TTL | eBay
470nm 4pcs of blue laser light >120mw high quality(FREE SHIPPING)-in Event & Party Supplies from Home & Garden on Aliexpress.com

These might be fake but also might mean there's a lower power/higher WL version...

 

[Tmack]

I knew this would be a hit. I'm glad I got it out to you guys that are willing to test them.

damn, looks like i might have to take the 635 out of my cyp cu host and go blue blue with it!(not a typo, i kinda hate 445)

[Atomicrox]

He removed the listing. For crying out loud, why do I always think twice?

 

[Tmack]

Aww what?
