1W Green Diodes

[planters]

What about Norty's color concerns. Is there some feedback from those that have used these 520 greens in projectors? Maybe hear what they say before purchasing? I guess if it isn't too expensive then you would be one of those that could report on this.

i use a 520 in my micro projector. the colors are a little more "argon like", but it's a pretty subtle color shift and is easy to miss.

You can make a beautiful brown that,s for sure.

You know, brown might not be bad if it was a choice. Anyone thought about adding 1 to 1.5 W of 520 to a DPSS by taking advantage of these polarized sources and PBS combining them? Keep the diode room temp for simplicity and rotate the diode rather than use a wave plate. Would a broader band green (dual band) improve the cyans and still produce nice yellow and orange (and brown)?

[edison]

with a wider bandwidth you have a wider variaty in colors. If you had red green and blue each in 2 different wavelenghts that would be a very nice projector. I think i have just found my next project

[kecked]

you also don't need to make them match in power. that way if the dpss craps out on thermal issues you still get a green and not purple.

You know planters you are too smart to be a human. You must be from up.....there

Actually, that was a possibility when the diodes were expensive, but I think that the higher space requirements will prevent me trialling it. It'll now be either all diode or all DPSS

There have also been a press release for 0.9W 475nm Nichia multi-mode diodes...

..I know this was kinda 'lost in the killer-sales wash' of this OP-thread, (..and probably-should spawn it's own thread...) but anyone make any progress sourcing a 'Quan: less than one-bajillion' supplier?.. 1W 475nm DI's will be *huge news* / progress..

The 475 would be killer.. maybe that would take care of the "brown" problem.. not sure I'm liking the thought of a brown laser beam instead of orange/ yellow .. :|

[Stiffler]

I doubt 475 will do anything for the brown problem, as blue isn't a component of orange or yellow.
