finesse.components.cavity.Cavity.FSR¶
- property Cavity.FSR¶
The free-spectral-range (FSR) of the cavity.
This quantity is defined as,
\[\mathrm{FSR} = \frac{c}{2L}, \]where \(c\) is the speed of light and \(L\) is the length of the cavity.
- Getter:
Returns the cavity free-spectral-range (read-only).
