Can solid state lasers produce the high energy needed here?

Yes.

I'm not really seeing any convincing numbers there. Mercury lasers seem to only be 10% efficient. I get that this is better than the lasers that were just used at NIF, but that still seems pretty far from useful.

Itβs useful enough to produce significant net energy if they continue with the gain scaling that ignition allows.
