Yep you got it, 1 trillionth of a second.
Somebody else will have to do the math formulas to see how that would relate in consumption to output of today’s lasers.
I think the biggest thing to come from the breakthrough may be that energy storage capacity.
Let’s add this clarification:
From the time the laser turned on, the first light out of the box traveled one third of one millimeter before the laser turned off.
