Peak Intensity of Gaussian Laser Pulses


This calculator computes the energy fluence (J/cm$^2$) and the peak intensity (W/cm$^2$).

Enter the pulse energy (J), the beam radius at $1/e^2$ intensity (cm), and the pulse duration (s).

The formulas used are:

Peak Intensity = $(\frac{1.88E}{\pi \omega^2 \tau})$

Energy Fluence = $(\frac{2E}{\pi \omega^2})$
