Excitation of Coherent Phonons in Crystalline B: theory for driving atomic vibrations by femtosecond pulses
In this paper we present experimental and theoretical studies of reflectivity oscillations of an optical probe beam reflected from a single-crystal of bismuth excited by 35 fs laser pulses at deposited energy density above the melting temperature. Coherent and incoherent lattice dynamics as well as electrons dynamics were investigated starting from the reflectivity changes, measured with high accuracy ΔR/R < 10. The complex behaviour of the reflectivity could not be explained in the light of...[Show more]
