The polarization response of neutral sub-gap photoexcited states in nonoriented nanopolyacetylene films was measured using a femtosecond photoinduced polarimetry technique. We show that the observed polarization signals are associated with a linear d

Using a photothermal laser deflection technique the profiles of laser-induced hyperacoustic pulses in single crystal germanium were studied at a subnanosecond time resolution. It is shown that the hyperacoustic pulses are excited due to an electron-d
