Abstract :
The model fits the fundamental-mode field better than the Gaussian distribution. It reduces the differences, caused by non-Gaussian field shapes, among methods for measuring mode field radius. Formulas are provided for calculating Petermann´s mode field radius from lateral offset, pinhole scan and VAMFF data.
