Optical rectification by ratchet transport in an asymmetric grating
AIP Advances, 2021 We report on electron ratchet transport’s manifestation in the optical rectification (OR) of an asymmetric grating. The photon-drag enabled effect is magnified by asymmetric photon scatterings and the induced optical nonlinearity associated with the ...

Generation of femtosecond pulse bursts at multiple-THz repetition rate by nonlinear self-compression in bulk KTP [PDF]
EPJ Web of ConferencesA chirped 470 fs pulse at 1030 nm was used to generate a phonon-polariton wave in bulk KTP by optical rectification. Phase modulation of the pump by the polariton wave resulted in generation of a burst of 20 fs pulses.
