reZonator is a software for designing of laser resonators and calculation of light beam propagation (as gaussian so as ray vectors) in complex optical systems.
This is the official port of reZonator to Qt framework. The goal is to make it open-source and cross-platform.
Currently, the version 2 is in beta state, it implements the most of functions of version 1 and also adds many new features. If you need some particular feature from version 1 that it no ported yet, or you need some new functionality, fill free to open an issue with a feature request.
