finesse.plotting.plot.plot_field¶
- finesse.plotting.plot.plot_field(modes, amplitudes, qs, *, x=None, y=None, samples=100, scale=3, ax=None, colorbar=True, **kwargs)[source]¶
Plots a 2D optical field for a given set of modes, modal amplitudes, and beam parameters.
x and y dimensions can be specified if required, otherwise it will return an area of scale times the spot sizes. When x and y are provided scale and samples will not do anything.
- Parameters:
- modesarray_like
Pairs of modes (n,m). Can be an 2xN array or a list or tuple of modes.
- amplitudesarray_like
Array of complex amplitudes for each mode
- qsBeamParam or Tuple(BeamParam, BeamParam)
Compex beam parameter object for x and y planes. If singular value give, qx = qy.
- x, yndarray, optional
Specify x and y coordinates to plot beam
- samplesint, optional
Number of sample points to use in x and y
- scalefloat, optional
Number of sample points to use in x and y
- axAxis, optional
A Matplotlib axis to put the image on. If None, a new figure will be made.
- colorbarbool
When True the colorbar will be added
- **kwargs
Extra keyword arguments will be passed to the pcolormesh plotting function.
