Figure Lengend Snippet: The scheme of noncolinear simulation. The interacting pulses have to be represented in overlapping spatio-temporal grids (red and blue rectangles) ( a ). Thus, the two UPPE describing propagation of the “blue” pulse along z 1 axis and “red” pulse along z 2 , have to be represented in a new coordinates system x ′ − y ′ − z ′. In this system the nonlinear terms can be calculated without interpolation. At the same time the spectral volumes (red and blue rectangles in b ) corresponding to the two pulses cannot overlap (unless the polarization of the two are orthogonal) so that none of the plane wave modes is represented in more than one grid.
