I'll keep this brief as I don't have power so on my phone.
Been thinking of direct doubling recently.
Aside from diode linewidth, what is stopping us from using a ring cavity to direct double?
I.E. Sending the pump source through a partly transmissive OC not at 90° (about 80°) and then that input would travel to a crystal cut to Brewster angle.
This would allow for an offset in the beam direction, and you could create a stable resonator without sending light back to the diode.
I will draw up something and upload it when I have power.
For now, google "ring cavity" for your brain food
