Femtosecond

The femtosegund spectroscopy unit uses its microscope and laser system to capture the movement of electrons.

A femtosecond is the unit of time that is equal to one billionth of a second, that is: In one second there are one thousand trillion femtoseconds. There are as many femtoseconds in a second as there are seconds in 100 million years (In 100 million years there are 3,153,600,000,000,000 seconds)

Abbreviated to fs.

1 fs = 1x10^-15 s
