- lolinder 4y agoAs I understand it they demonstrated a net gain relative to the energy output by the laser, but not relative to the energy put into the laser. 1% is correct for the actual efficiency given the cost to generate the laser. (Yes, that distinction does seem important and wasn't brought out by the news reports.)
