Pouring gigawatts of laser light through fiber sounds pretty hard, especially if you want to have electricity for the end consumer, not light.

If sticking to a single frequency, the main loss is in producing the light in the first place as the new fibers can take a lot of power and conversion from light back to electricity can get above 90%, but laser efficiency is still pretty crap.

If laser efficiency were good enough for this we would have laser fusion.

I didn't realise that the laser's inherent inefficiency was the main loss in laser fusion, though it would make sense.
