Finesse is an interferometer simulation program. It calculates light amplitudes in a user-specified interferometer configuration and can generate output signals for various photo detector types. All calculations are done in the frequency domain, Gaussian beams can be used to model spatial effects. Finesse is open source software distributed for OSX, Linux, and Windows. It has benefited from years of employment by scientists working on gravitational wave detectors.

Finesse is written in C and is compiled into a single binary executable called 'kat'. Today the preferred method of using Finesse is from Jupyter notebooks, using its Python wrapper Pykat.

We also have a 'Finesse' jupyterhub kernel in our jupyterhub at
