finesse.components.cavity.Cavity.generate_abcd_str

Cavity.generate_abcd_str()

Generates a string representation of the cavity round-trip ABCD matrix operations.

This can be useful for debugging purposes as the returned string will correspond exactly to the operation performed internally for calculating the round-trip matrices.

The format of each matrix symbol will be <comp>__<from_port>_<to_port>, e.g. the reflection at the rear (port two) surface of a mirror named ITM would be represented as ITM__p2_p2. The matrix multiplication is denoted via the @ symbol.

Returns:

abcd_strstr

A string representing the operation to obtain the cavity round-trip ABCD matrix (in either plane).
