Gaussian Beam Calculators
Gaussian Beam Radius
Relevant Relations
\(w(z) = w_0 \sqrt{1+\left(\frac{z \lambda M^2}{\pi w_0^2}\right)^2} = \frac{\lambda f M^2}{\pi w_\mathrm{L}} \sqrt{1 + \left(\frac{z \pi w_\mathrm{L}^2}{\lambda f^2 M^2} \right)^2} \)
Gaussian Pulse Peak Intensity
Relevant Relation
\(I_0 = \frac{2E}{\pi w^2} \sqrt{\frac{\mathrm{ln} 16}{\pi \tau_\mathrm{p}^2}} \)
