Virgo model

Interferometer for Finesse 3. Can be used with the finesse-virgo package.

Getting started

For simple use, layout file can be used. A layout is a list of files separated by new lines to load in order to create a finesse3 model. The "simple" model present some quick model with little components which allows to manipulate easily a finesse model. The "finesse-virgo" model correspond to the model available in the finesse-virgo package.

Example

Code example to build a Virgo model with these scripts.

    from pathlib import Path

    layout_file = Path("layout/finesse-virgo/no_benches") # path to layout file
    with layout_file.open() as f:
        files = f.read().splitlines() # convert layout file to list of path
    virgo = Virgo(
        files_to_parse = files, # create model with the given list of path
    )

The advantage of this is the control we have over the interferometer simulation, and the readibility. Tracking change is also easier, variable definition being detached from setup configuration.

Sections

Katscript files are organized in different types, which are values, optical setup, link, cavities definition, degree of freedom, detectors and after variables.

variables

Contains values used in the setup.

It can defines variable which depends of components in the setup for preprocessing (finesse-virgo package for example) too.

components

Defined part of the optical setup (Laser, Mirror, etc.) or set of parts.

links

Link together parts of the optical setup defined before

cavities

Defines Finesse3 cavity

degree of freedom

Defines Finesse3 degree of freedom

detectors

Add Finesse3 detectors
