Projects / Finesse


Finesse is a numeric simulation for laser interferometers using the frequency domain and Hermite-Gauss modes. It is easy to use for students. For basic use, including graphical output, no commercial software is required. The implemented physics are well documented in a 180-page manual. Simple examples are provided. Finesse can be used to compute a great variety of interferometer signals for control systems, including longitudinal control, alignment control, and thermal compensation.

    Release Notes: This is a major upgrade focussed on implementing radiation pressure effects on suspended optics and a full treatment (in the two-photon formalism) of the quantum noise of interferometer signals. New features include squeezed light sources, quantum noise detectors, and the ability to apply mechanical response functions to optical elements.

      Release Notes: The coupling of multiple frequency components has been completely rewritten. Now all laser fields and modulator sidebands are computed simultaneously, allowing correct modeling of `sidebands of sidebands' (such as those created by two modulator components in series). This is mostly a bug fixing release in preparation for the implementation of radiation pressure effects.
