I can dream, can't I? Imagine what any one of us would have said about having these 473nm diodes just a year ago. I have done some research into the 607nm process and it seemed that the limiting factor was demand for it. Rgob displays anyone? Iirc the articles I had read on it used a nd:ylf Crystal pumped with 445 which directly and relatively efficiently caused it to lase at 607. Seemed a lot simpler than most of the current processes however it also seemed to be in its infancy at the same time.
Maybe one day...
I'm pretty sure it's Pr:YLF that does 607nm. Alternatively, they can do 604nm with PrAYAC setups but if I recall that process is way less efficient and the crystal is way harder to cultivate.
I don't have a lot of faith in the pseudo DPSS thing that orange process is... That said... I think we will eventually see orange lasers, but using diodes instead. Commercial lighting will inevitably move on to at the very least attempt laser lighting. You can buy 622nm diodes for around $500-600 right now as it is.
