We already have lasers which are an order of magnitude more efficient than the one the lab was using. This is about a proof of concept, not about being an actual power plant. Also, as I understand it, the whole thing scales up very well. Now that we can "ignite" fusion in the little pellet used for testing, we can scale up to ignite a larger amount of fuel in order to get out much more energy.
