Finesse 3.0b3-1-g0da777fd

This is a beta release of Finesse 3.

Please report any issues.

Overview

Finesse is a fast and easy to use Python-based interferometer simulation program. It uses frequency-domain optical modelling to build accurate quasi-static simulations of arbitrary interferometer configurations.

For convenience, a number of standard analyses can be performed automatically by the program, namely computing modulation-demodulation error signals, transfer functions, quantum-noise-limited sensitivities, and beam shapes. The optical system can be modelled using the plane-wave approximation or Hermite-Gauss modes, allowing the computation of optical systems like telescopes or the effects of mode matching and mirror angular positions.

Finesse provides a large set of utility functions for ease of use when handling complex simulation tasks, for example:

  • chained simulations,

  • advanced plotting of outputs,

  • automated simulations,

  • the use of Jupyter notebooks to document simulation tasks,

  • and much more!
