Coherent transfer of information within the laser field through interferometric FSHG. An amplitude filter is inserted in the longer Michelson arm before the nonlinear stage; XFROG spectrograms featuring the amplitude distribution among both pulse sequences: (a) fundamental pulses and (c) second-harmonic pulses. (b) Spectrum (solid line) and phase (dashed line) of individual pulses (black F1, red F2) retrieved from XFROG reconstruction. The spectrum of the delayed pulse at ω0 (F2) has a sharp cut-off. (d) The sharp cut-off is transferred from F2 at 2ω0 to two pulses at two different delays, H12 and H2. Notably, H12 is leaving the system 2 ps before F2.
