Reply to comment by JiminyDickish in Why are green and red laser pointers so cheap and available, but yellow ones not so much? by SurprisedPotato

And while green is typically doubled, I thought Nichia came up with the gallium nitride blue laser which is direct for low power lasers.

We have direct blue and direct green diodes now, 450nm and 520nm respectively.

Edit: the direct blues are 5+ watts per diode and the green is at about 1.4 watts per diode so not that low powered
