Question

The output of ruby laser has pulse duration of 10 ms and average output power of 1 mW per pulse. How much energy is released per pulse?​

Answer 1

Given that,

Time = 10 ms

Power = 1 mW

We need to calculate the energy released per pulse

Using formula of energy

$E = P\times t$

Where, P = output power

t = time

E = energy

Put the value into the formula

$E=1\times 10$

$E = 10\ mJ$

Hence, The energy released per pulse is 10 mJ.
