The VirtualLab Laser Resonator Toolbox is for designing and simulating continuous-wave solid-state lasers, both 3-level and four-level configurations.

It models fundamental and higher order eigenmodes of stable, unstable and ring resonators. Output power and beam quality (M²) are calculated, taking into account thermal lensing, birefringence, and nonlinear gain saturation.

Fully-vectorial formulation of the Fox and Li method is combined with a vectorial beam propagation method (vBPM), enabling calculation of the dominant transversal eigenmode of realistic cw solid-state lasers. The vBPM is used to simulate light propagation through the active medium including the effects of thermal lensing, stress-induced birefringence and nonlinear gain saturation.

Intracavity components, such as: mirrors, lenses, polarizers, apertures, and index-modulated media can be included.

The Laser Resonator Toolbox works along with the Starter Toolbox (in VirtualLab Fusion Basic or Advanced) to include all the optical elements in a lightpath, in addition to the laser resonator. The Starter Toolbox can include sources, all optical elements, detectors and analyzers. It includes parametric optimization for the entire optical system, such as distances, positions, sizes, angles, wavelengths, and many more parameters.
VirtualLab Fusion is an integrated software suite of programs for connecting solvers and propagation methods for all the microscale and macroscale components in an optical system.

Rigorous analysis of components, such as gratings and metegratings, if needed, can done with the VirtualLab Grating Toolbox, which is included in VirtualLab Fusion Advanced.
Diffractive beam shapers, if needed, can be modeled with either Diffractive Optics Toolbox Silver or Gold versions.
Diffractive lenses and metalenses can be modeled with Diffractive Optics Gold version.
