Nd:YVO4 questions

The way to overcome this is to use an output coupler with a radius of curvature, rather than a flat mirror or coating.

Why not grind the end of the KTP itself into a curve?

I dont think that would work

Plus, with that kind of power the KTP probably couldn't take all the 1064nm power. Normally it goes through, obviously, and since it's transparent to the 1064 it's not stressing it too badly, the OC and HR mirrors take most of the stress.

So what would be the most power I could use with my ktp that I have?

You could make a whole bunch (assuming it is a high quality crystal), but you are going to need a very complicated cavity design.

Start researching z-fold cavities and how they work. You could also pump the vanadate on both ends and make a ring cavity.

If you use a simple linear cavity you still can get green, but your efficiency and overall output would be far better with a longer cavity

Yeah but that's with a q-switched laser, which makes using a NLO incredibly easy. I bet you'd be VERY hard pressed to get that to double into 532 with a CW laser unless you had just a TON of raw power.
