Characterizing ultrashort pulses with photon energies above 1.12 eV based on transient absorption in silicon thin films

Frequency-resolved optical switching (FROSt) is a phase-matching-free characterization technique for ultrashort pulses based on transient absorption in semiconductors. So far, this technique has been limited to characterizing pulses with photon energies smaller than the bandgap of the semiconductors...
