Modeling Physical States in Optical Cavities

The VirtualLab™ Laser Resonator Toolbox is designed to solve your resonator modeling tasks. For LASCAD users it offers extended techniques for analyzing laser resonators using Fox-Li and Arnoldi algorithms. In a typical application scenario, you are asked to specify your laser resonator configuration by selecting components, such as mirrors, interface sequences, index-modulated media, laser crystal, diffractive optical elements, ideal components like the ideal lens or a generalized Jones matrix. You then begin the eigenmode analysis to obtain the fundamental mode and its eigenvalue. All parameters of this mode can be detected, including the beam waist and M² value. Polarization effects can be included, as well as the bandwidth of transition levels.


The Laser Resonator Toolbox provides you with powerful tools for the analysis of laser cavities. The flow chart system concept gives you high flexibility in modeling laser resonators. Powerful eigenmode algorithms allow a fast investigation of laser cavities.
