- Аннотация: We successively probed energy transfer stages after femtosecond laser excitation of a bulk of crystalline dielectrics from femtosecond to nanoseconds timescale. We observed a change in the frequency of THz phonons from 1.4 to 4.6 THz, quasi-resonantly excited by laser plasma oscillations under tight focusing (NA~0.4) of intense femtosecond laser radiation in a bulk of quartz. In BaF2 a 15 ps time delay of the significant increase in the phonon wave amplitude was shown. In LiF the energy transfer between many phonon modes is clearly visible.
