Some neodymium glass lasers can provide 100TW of power in 1.0 ns pulses at a wavelength of 0.26 micrometers. how much energy is contained in a single pulse?

E = 10⁵ J

Explanation:

given,

Power, P = 100 TW

= 100 x 10¹² W

time, t = 1 ns

= 1 x 10⁻⁹ s

The energy of a single pulse is:-

Energy = Power x time

E = P t

E = 100 x 10¹² x 1 x 10⁻⁹

E = 10⁵ J

The energy contained in a single pulse is equal to 10⁵ J
