finesse.components.cavity.Cavity.loss

property Cavity.loss

The round-trip loss of the cavity as a fraction of the incoming power.

This quantity is computed via,

\[L = 1 - \prod_{\mathrm{i}}^{N_{\mathrm{refl}}} R_{\mathrm{i}} \times \prod_{\mathrm{i}}^{N_{\mathrm{trns}}} T_{\mathrm{i}}, \]

i.e. one minus the product of all reflections multiplied with the product of all transmissions for a round-trip of the cavity.

Getter:

Returns the fractional round-trip cavity loss (read-only).
