Given Information:
Energy of laser pulses = E = 100 mJ = 100×10⁻³ Joules
Time = t = 1 ns = 1×10⁻⁹ seconds
Required Information:
Instantaneous power = P = ?
Answer:
[tex]Instantaneous \: Power = 100 \: Mwatt[/tex]
Explanation:
The instantaneous power is the power dissipated at any instant of time whereas the average power is the power dissipated over a given time interval.
The instantaneous laser power during each pulse is given by
[tex]Instantaneous \: Power = \frac{E}{t}[/tex]
Where E is the energy of the laser pulses and t is the time that each pulse lasts.
[tex]Instantaneous \: Power = \frac{100\times10^{-3}}{1\times10^{-9}}[/tex]
[tex]Instantaneous \: Power = 1\times10^{8} \: watt[/tex]
or
[tex]Instantaneous \: Power = 100 \: Mwatt[/tex]
Therefore, the instantaneous power of each pulse is 100 Mwatt.
