Reply to comment by _GD5_ in Why are green and red laser pointers so cheap and available, but yellow ones not so much? by SurprisedPotato

Indeed, the diodes for cyan and yellow are very expensive and have only very recently been publicly available

Is this a recent breakthrough (similar to blue diodes 10 years ago), or is it something that has been known for a while, but just far too expensive for the benefit that it provided?

Could we see the cost of yellow diodes drop dramatically over the next decade?
