They lose so much in the lasers because they're using lasers from the 1990s, which are only 0.5% efficient. Equivalent modern lasers are over 20% efficient. From the input power being 130X more than the fusion output, modern lasers would turn that into about 3X. That's kinda promising because the fusion output seems to have nonlinear scaling; they increased laser power 8% and got 230% more output. This is why there are startups now pursuing laser fusion for commercial energy.
