Title | Finesse 3 |
Description | 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. |

Open Source License? | Yes |
Impact | Finesse has been widely used across the gravitational wave detector instrumentation community for modelling, e.g., transfer functions and error signals, in current and proposed gravitational wave detectors. The new version of Finesse that this record refers to will enable more flexible usage of the software with powerful extensions for controlling virtual interferometer configurations and modelling opto-mechanical systems. |
