As far as the hobbyist community is concerned of course. I'm sure they must still have some lab uses.
I recently picked up this 5W 465nm build from alien laser and my eyes honestly cannot tell the difference between this color and the color my blue RPL put out(before I re purposed the host) It's pure bright blue without a hint of purple. Looks indistinguishable from 473 except for being several hundred times more powerful.
Pros of 465nm:
Better stability.
Cheaper.
Much much much higher output.
No need for exotic crystals that go bad over time or anything like that.
Cons:
Bad beam specs.
Higher power units like this one heat up quickly and only have a duty cycle of around 30 seconds.
I suppose I would need to see what this wavelength looks like in the more conservative 1 watt range. I understand that the wavelength drifts upwards at higher output levels.
Blasting a tree 150-200 feet away with 5 watts of blue:drool:
