reZonator is software for designing laser resonators. It supports standing wave resonators, ring resonators and single pass optical systems. A number of optical elements are supported - ranges, lenses, mirrors, crystals, user defined also. It is possible to construct arbitrary optical system from proposed elements. Software can calculate stability maps, plot beam parameters at any position inside the system. There are other analytical functions.

reZonator is a software for designing laser resonators, and simulation the propagation of light beams in complex optical systems. reZonator supports standing wave laser cavities and running ring resonators, as well as regular single-pass systems, e.g. pump roads or beam expanders. M? beam quality factor is also taken into account for single-pass systems. reZonator's elements catalog contains a number of basic optical elements - ranges, lenses, spherical mirrors, crystals etc. The ABCD ray matrix algorithm is used for simulation of optical elements so also user defined elements are available. It is possible to construct an arbitrary optical system from proposed or user defined optical elements. reZonator automatically creates a rendition of the system under investigation - almost you could sketch it on a paper sheet or your drawing board. For advanced system optimization rezonator can compute cavity stability maps versus values of one or two (contour maps) any parameters of any element. It is possible to specify arbitrary contour lines for contour stability map. Also automatical computation of stability boundaries is provided. reZonator can plot the size and wavefront curvature radius of gaussian beam over one or a few elements, astigmatism is also calculated. It is possible to compute beam size at any position inside the system. Automatical determination position and size of the waist at element where it is, calculation radius of diffractive divergence and other parameters of gaussian beam are provided. Adjustment tool allows you to smoothly change any parameter of any element - just like you rotate a screw of some mirror mount or a translating stage. Any results are instantly recalculated while parameter value is changed. Other convenient and useful tools and functions also available - repetition rate, beam parameters at all elements, misalignments of elements, "freezing" results, full plot customization, copying results to clipboard, and more.
