Yes, and lasers that do exactly that have advanced very quickly. We're up to multi-petawatt picosecond lasers now. We're getting high repetition rates instead of the once or twice per day of NIF, by using laser diodes in place of flashlamps. There are dozens of extreme laser facilities operating or under construction all over the world. And if I'm not misinterpreting this, efficiency is as high as 60%:
