IIRC it's about 2 MT/s.

If you'd focus the entire solar output on Jupiter it would seem quite easy to
achieve significant escape rate, given that it's all hydrogen, and escape 
velocity is only 60 km/s.

Sun is harder because if you trap the radiation it will heat up and bloat up and
simultaneously reduce the fusion rate. Perhaps you can blow off chunks of
photosphere, by periodic/asymmetric feedback of the solar output.

I don't see how this is a controlled disassembly process, though. Ditto
Jupiter.
