And still lower than other laser systems using inertial confinement. If I'm reading NIF's recent paper right, they're claiming Q_a of above ~1.4, or Q = ~0.28
Edit: Wikipedia suggests that they were using a different method to calculate Q, only measuring the power input to plasma vs output from fusion, not including system losses. So that figure is probably not directly comparable.
> the NIF used ~477 MJ of electrical energy to get ~1.8 MJ of energy into the target to create ~1.3 MJ of fusion energy
