LaserCalc is an Open Source xWidgets application for the calculation of optical beam paths and laser resonators based on Gaussian beam matrix optics. In addition beam paths can be optimized to match given beam parameters (mode matching).

In this case the fundamental TEM00 eigenmode is automatically calculated. In addition the stability of the resonator is derived. Finally the modematcher module tries to find the (nearly-)best solution for the transformation of a beam to given target parameters based on a list of available optical elements. It tries all possible element combinations together with an optimization of the respective distances from each other.
