Great. The price of oil is at record highs and now this.
Oh, another important question: is it a compact fluorescent bulb?
It does not use much energy.
Power is energy divided by time, so a pulse of one Watt that lasts a second has one Joule of energy. Take that same Joule and pulse it not in a second, but a nanosecond (one billionth) and the power in Watts is 1,000,000,000.
This laser is “a tenth of a trillionth of a second” which sounds like 10 femtoseconds, .00000000000001 second, so the total energy does not need to be a lot of Joules to be “the most powerful (in Watts) in the world”.
The whole setup probably runs on less than a kilowatt or two, and a lot of that will be cooling fans and water pumps.
