How To Calculate Peak Power Of Pulsed Laser. When working with pulsed laser sources laser developers and scientists are often interested in knowing the peak power the highest power output from the laser. Pulse Energy Joules Average Power Watts Repetition Rate Hertz Lets put some real values in there and assume that you are working with a laser that has a fixed 200 W output and a repetition rate that can be tuned from 20 Hz to 1 kHz.
The peak intensity and fluence of the laser is given by. A Gaussian pulse shape is assumed. Average power provides no information about peak power period or pulse width.
When working with pulsed laser sources laser developers and scientists are often interested in knowing the peak power the highest power output from the laser.
Pulse amplitudes E exp t i I t φ t Removing the 12 the cc and the exponential factor with the carrier frequency yields the complex amplitude Et of the pulse. Tophat calculations are for ideal tophat laser beams. I know the duration of the pulse t in seconds and I know the peak current Ipeak in Amps. This calculator assumes square pulses.
