finesse.components.cavity.Cavity.S

property Cavity.S

The resolution of the cavity in both planes.

Cavity resolution, \(S\), is defined by,

\[S = \begin{cases} \frac{\psi_{\mathrm{rt}}}{2\pi} \mathcal{F}, & \text{if } \psi_{\mathrm{rt}} \leq \pi\\ (1 - \frac{\psi_{\mathrm{rt}}}{2\pi}) \mathcal{F}, & \text{if } \psi_{\mathrm{rt}} > \pi, \end{cases} \]

where \(\psi_{\mathrm{rt}}\) is the round-trip Gouy phase and \(\mathcal{F}\) is the cavity finesse.

Getter:

Returns a numpy.ndarray of the cavity resolution in the tangential and sagittal planes, respectively. (read-only).
