UPE.nonlinear_operator#
- UPE.nonlinear_operator(a_v)[source]#
The action of the nonlinear operator on the given pulse spectrum.
This model implements the Kerr and Raman effects, as well as 2nd- and 3rd-order sum- and difference-frequency generation.
- Parameters:
- a_varray_like of complex
The root-power spectrum of the pulse.
- Returns:
- ndarray of complex
