finesse.tracing.tools

Beam propagation tools for use outside of a simulation context.

The recommended function for most use-cases is propagate_beam() (and propagate_beam_astig() for astigmatic beam propagations) which traces a beam through a specified path of a model. See Beam propagation for details and examples.

Functions

acc_gouy([from_node, to_node, via_node, ...])	Computes the accumulated Gouy phase along a specified path.
compute_abcd([from_node, to_node, via_node, ...])	Computes the composite ABCD matrix through a given path.
compute_cavity_mismatches(model[, cav1, cav2])	Computes the mismatch parameter (see BeamParam.mismatch() for the equation) between cavities of the model.
handle_symbolic(*args, symbolic, simplify, ...)	Handles logic for the 'symbolic' argument for propagate_beam() and compute_abcd().
propagate_beam([from_node, to_node, ...])	Propagates a beam through a specified path, returning dictionaries of the beam parameter at each node and component.
propagate_beam_astig([from_node, to_node, ...])	Propagates the beam through a specified path over both the tangential and sagittal planes.
