I don't know if this is pumped or directly driven.

November 23, 2012...Nichia Corporation reports that it has successfully developed a high-power pure green laser diode which has optical output power higher than 1W with 525nm lasing wavelength. first time in the world,which will be applied for display application such as Laser TV. Nichia reportedly optimized the epi-structures based on c-plane GaN substrates to achieve the improved performance.

Nichia says that as a result, the company's new green laser diode achieved 10 times greater optical output power and 1.5 times higher Wall-Pulg-Efficiency*3 compared with the current lower power green laser diodes based on GaN. Notably, the high-power pure green laser diode development completes the fundamental three colors semiconductor laser light source with 1W range output power for each color. Nichia asserts that the three color laser light source will open the application of laser TV as well as laser projectors with the much lower power consumption and the higher color gamut.

It refers to it as a diode, so i would think that it is just that. Not a dpss. Can't wait to see one harvested and in a host.

oooh good thing I held off on a 1W green DPSS. Nice find! can't wait till we push these to 2W :evil:

Edit: information link

Gonna keep my eyes open for more info. They say it's over 1W, looking like it's a >1W typical output power. From what I know, the green diodes also lower in WL as the power goes up... so maybe we will get 510's after all.

Yeah yeah, cheap green diodes have been "just around the corner" for years now.

Keep faith brother ^^ you got to believe!

Nah serious, i hope this would be (Will be) the future.

But hey.. i enjoy the lower powered ones just aswell :wave:

Cheers, Sm.

Hey if they plan on using these for TV's we shouldn't have any problem finding them in the future. I just hope they're single mode...

Imagine a TV/projector with multiple blue, red, and green diodes. Make's me excited for the future of the hobby, but then again the more mainstream things get the higher risk we'll face with getting more strict laws. I'm more fearful of a 100mW green getting into the wrong hands than a 1W blue when it comes to aircraft incidents.

Hopefully the prices stay >$150 to keep the spontaneous idiots from buying these.

I say $200. Obviously I would love them to be cheaper but the cheaper the hobby gets the more idiots will get there hands on high power lasers.
Keeping the price around 150+ keeps a lot of idiots away.

People never believe me when I say I have a laser that lights paper on fire, until I show them the video, first thing said is "how much does that thing cost?"
You should see their disappointment when I tell them $250

I've seen people literally get giddy about a burning laser but when they learn the price tag it's funny to see how quickly they no longer want one.

Hahaha. Same here. 90% of the time when I tell people how much these lasers cost they end up looking like a kid who didn't get the gift he wanted on christmas morning.
