reZonator

reZonator is a handy application developed to help you design laser resonators as well as create simulations of the propagation of light beams in complex optical systems. The program supports standard single-pass systems such as a beam expander or pump roads, for instance, but also running wave and standing wave laser cavities.

The app is quite versatile and hence, allows you to build the optical system you need using either the templates available or one that features user defined elements. Regardless of the optimal elements employed, the application creates the rendition of the system under investigation automatically. Moreover, whether you use spherical mirrors, ranges, crystals or lenses, the elements are simulated into the system using the ABCD ray matrix.

A noteworthy function is the waveform calculation, considering that the program can automatically plot the wavefront curvature radius and the size of the Gaussian beam over a single or multiple elements. The position and size of the waist at element based on its position, astigmatism, diffractive divergence and other parameters of the beam are automatically calculated.

As you would expect, the application allows you to make any modifications to the system. Thanks to the adjustment tool you can change any parameter of any element and the results are instantly re-calculated using the new value.
