A NdYAG operates in pulsed mode with an energy of 02 J per p

A Nd:YAG operates in pulsed mode with an energy of 0.2 J per pulse, and a pulse repetition rate of 50 Hz. Each laser pulse lasts for 1.5 ns

a) What is the instantaneous laser power during each pulse?

b)What is the average power output of this laser

Solution

Given :-

E = 0.2 J

t = 1.5 ns = 1.5 x 10^-9 s

f = 50 HZ

A)

E = Ppeak x t

Ppeak = E/t

Ppeak = 0.2/1.5 x 10^-9

Ppeak = 0.133 x 10^9 W

b)

Pavg = E x (1/t) -----------(1/t) = f

Pavg = E x f

Pavg = 0.2 x 50

Pavg = 10 W
