I was just curious is they make diodes at 473nm yet? or is this not possible? Does anybody here make high powered portable blue lasers here? like 100mw plus?
I have a feeling that diodes will never be able to replace DPSS. The beam quality just can't be beat for the cost.

There are some 50 mW 455 nM around these parts at ONLY $688 per each !!!!

Sounds like an insane amount for a diode, but frankly, it isnt even that far away from 50 mW 473 dpss units on the market. Considering the smaller form factor, it might even be worthwhile.
On the other hand, now is not the time to buy any of these. With the laser projectors coming rapidly, expect prices to drop in the short run. I wouldnt be that surprised to see these diodes on the market for bluray-like prices within just a few years.
I suppose we will be ripping apart projectors for the diodes as we are bluray drives right now soon enough. The diodes might not be 473, but the 440-450 range would be very nice to have as diodes, and fill the gap in true-RGB projection on a budget.
Nichia have them in their product catalog, but are in "engineering sample" status (they mean probably "still prototyping") ..... and i don't dare to imagine how much they can ask you for a sample (probably 1500 or 2000 $, LOL)
"aquamarine" 473nm diode ..... and "sky blue" 488nm diode .....
Wow! I've heard of 450 nm diodes before, but I didn't know there were actual 473 nm diodes. Technology really is advancing fast.
Diodes have been made in the entire wavelength range from below 380nm (UV) up to 531nm (very green).
Really!? I've never heard about most of these.
Does anyone on this forum have one of these diodes? (Except the Blu-ray)
