Re: New Nichia 9mm 1W 520nm diode
Very exciting, can't wait to try one!

Being that now all 3 diodes red,blue & green will now have similar beam profiles would it then be easier to not have any overlap with red and blue over the green like you would have if you used a solid state 532nm system since its beam profile is more round.?
A few notes about diodes.
520 9.0mm 1.0W (46 x 11) Nichia ( Will be ok in laser projectors)
445 9.0mm 1.0W (44 x 14) Nichia ( Proven to be ok in laser projectors )
635 5.6mm 0.5W (35 x 7 ) Mitsubishi ( Proven to be ok in laser projectors )
Are those facet dimensions?
If they are, the ratio from reds (7/35) ~= the ratio from greens (11/46).
I would expect divergence very similar to that of the red diode.
$ per mW if not over overpowered but yep they are not so cheap yet. Maybe if a Video projector starts to use them, the price will fall to < 50 dollars. I suspect given the design and specifications is very similar to the 445 1W, I suspect they are destined for some video projector.
Let's see. If the blue 9mm is rated at 1.6W at 1.7A and we get over 3W driving them at 2.3A or more.... I wonder how much green we can get if we drive this over 2.3A. :eg:
No need to wait for one or two years. I bet these will beat DPSS $/W in 6 months. Maybe not the low power greens (<100mW), which are really cheap on ebay, but I'm almost certain about the high power ones.
In two years I guess DPSS 532nm will be used only in applications that need WL stability or a better beam profile.
Lol its at a $ per mw. Just as expensive as DPSS at the moment. I would be so happy if the price of these dropped below 200 EVENTUALLY. I can wait a year or two.
