Abstract (EN):
We present a theoretical model and 2D numerical simulation of cascaded four-wave mixing of femtosecond pulses in bulk chi((3)) media, evidencing the importance of 2D interaction geometries in the efficient generation of frequency-converted pulses. Octave-spanning spectra and pulse synthesis down to the sub-two-cycle regime is demonstrated without the need for complex amplitude or phase control, in agreement with experimental measurements.
