NLSE

class pynlo.model.NLSE(pulse, mode)

Bases: Model

A model for simulating single-mode pulse propagation with the nonlinear Schrödinger equation (NLSE).

This model only implements the 3rd-order Kerr and Raman effects. It does not in general support 3rd-order sum- and difference-frequency generation.

Parameters:

pulsePulse

The input pulse.

modeMode

The optical mode in which the pulse propagates.

Methods

propagate(a_v, z, z_stop, dz, local_error[, ...])	Propagate the given pulse spectrum from z to z_stop using an adaptive step size algorithm.
nonlinear_operator(a_v)	The action of the nonlinear operator on the given pulse spectrum.
update_linearity([force_update])	Update all z-dependent linear parameters.
update_nonlinearity([force_update])	Update all z-dependent nonlinear parameters.
