Propagation of a 3D Gaussian Beam Laser Pulse

Laser systems are an important application area in modern electronics. There are several ways to generate a laser beam, but they all have one thing in common: the wavelength is determined by the stimulated emission, which depends on material parameters.

This model is a 3D time domain simulation of Gaussian beam pulse propagation. The YAG (lambda=1.06 µm) laser beam pulse has its waist of the beam is inside the domain and the input and output boundaries are bent according to the spherical wave fronts of the Gaussian beam.

Collage showing the x component of the electric field, small figure shows a cross sectional plot of the electric field at the different time steps. After 20 fs the pulse has passed the minimum waist and soon reaches the output boundary.
