I feel you are looking on the wrong numbers.
Yes, individual photons are hugely more energetic, and the process is lossy, but it does not mean the process will consume a lot of energy - very few might be needed.
You previous calculations are for creating light pressure sufficient for fusion, that's a uniquely energy consuming process, You can't reuse those numbers here because they are not trying to crush Uranium atoms together.
But likewise I could not find concrete details for the proposal.
