1. Beam Optics

Optical Beams

Paraxial beams

  • Paraxial wave equation
  • Gaussian beams as solution of the paraxial wave equation

Gaussian beams

  • Key parameters of a Gaussian beam and their physical properties (beam intensity, width, divergence, wavefront curvature, Gouy phase shift)
  • q-parameter and ABCD law for Gaussian beams 
  • Higher order Gaussian beam modes
  • Elliptic Gaussian beams
