    Photoinduced gratings in a Sn2P2S6 ferroelectric crystal with the period depending on the optical pump power

    The light scattering in the form of ring structures in Sn2P2S6 crystals at the propagation of intense laser pump radiation along the b crystallographic axis is detected. Radiation passing through a crystal is com...

    Photoinduced dynamics and femtosecond excitation of phonon modes in ferroelectric semiconductor Sn2P2S6

    The ultrafast dynamics of electrons and phonons excited by femtosecond light pulses in ferroelectric semiconductor Sn2P2S6 is investigated using the optical pump–probe technique. It is demonstrated that a soft mo...
