cavcalc.functions.symmetric

Physical geometric-like parameter functions associated with symmetric optical cavities. Most properties here are expressed only in terms of the g-factor of the cavity mirrors, as inter-dependent relations between these properties are computed via target chaining in the core cavcalc code.

Note

Whilst these underlying functions are publicly accessible, it is recommended that you instead use the single-function interface calculate() for computing any of the cavity properties that you need; as that will result in a nice output object for accessing results.
