Spatial and time characteristics of a four-wave radiation converter in a parabolic waveguide with resonant nonlinearity
Spatial and temporal characteristics of a degenerate four-wave converter in a multimode waveguide with resonant nonlinearity in a scheme with counter-pumping waves are analyzed using the time response function and the point spread function.For single-mode pump waves with equal mode numbers, the dependences of the time response width on the waveguid
