Scientists Are About to Fire Up The Most Powerful Laser in The US



The most powerful laser in the US right now is getting turned on to send its first pulses this week – enabling researchers to get a new level of insight into plasma physics and particle accelerators.

Known as the Zetawatt-Equivalent Ultrashort pulse laser System (ZEUS), it produces an ultra-short, extremely powerful pulse of just 25 femtoseconds. A femtosecond is a quadrillionth of a second – or to put it another way, a femtosecond is to a second what a second is to about 31.71 million years.
