Can't wait until green DIODES are available to us for a reasonable price!! :drool:

They will have shitty beam specs don't forget. Probably worse then the 445s.

Are they multi-mode?

I don't even know the wavelength, but there's a really good chance they are multimode.

Depending on the operation of the projector, it may require single-mode operation.
We'll just have to wait until they are available.

I'm sure another company will release a green projector sooner.

No. Remember the casio diodes are multimode for more power, and that's ok because they're just the lightsource for a DLP chip. This projector is a ''flying spot'', so it needs a well-collimated clean dot. So it'll be single- mode.
Unless this isn't the projector I was thinking of, but I think it is.

It's definitely DLP.

Nope, it's not. I went back and looked again. The AAXA projector is the DLP-based projector (well, not actually DLP, but LCOS, similar idea though, where the laser is simply a light source and another piece of technology is forming the whole image at once). The Microvision Showwx is a raster-based "flying spot" projector. So it has to use single-mode lasers.
Here's a thread on this very forum that talks about the rastering of the Microvision projector, and also compares it to the AAXA projector on the second page. The last post is even a high-speed video played played back at normal speed of the Microvision projector, which shows the dot rastering across the image.

So whatcyoo sayin' is= epic power, epic color, epic mode laser diodes?
Dude, I haven't felt this feeling since I found out about those blue diodes.
I'll go burst open out of sheer impatience.

I wouldn't say epic power. For a single mode diode, you're not going to get a ton of power. The blue diodes we have are multimode for that reason, to get more power. It's all relative, of course, but you can basically say that if it's single mode, it won't be amazing power.
Microvision's projectors are designed to be small anyway, not powerful. The green diode will make it smaller and more efficient, but not a lot more powerful in all likelihood.

That's what I'm saying, epic powa for single mode. If 445nm's are only 50mW but single mode, I'd still pay $50 for them.
Imagine greens being at least that.

Aren't blu-ray diodes single mode, and recent 12x burners capable of nearly one Watt?
I hope one day this will be achievable in direct green diodes. :drool:

Yeah, a couple of single-mode 405 nm diodes have broken the 1 W barrier. I don't expect them to last very long, though.

We need yellow diodes or cheaper yellow dpss
