Lifetime of optical phonons in fs-laser excited bismuth

Boschetto, David; Garl, T.; Rousse, Antoine; Gamaly, Eugene G; Rode, Andrei V

Description

This paper presents experimental and theoretical results on the temperature-dependent optical response of a single crystal of bismuth to excitation by femtosecond laser pulses. We demonstrate that the measured damping rate of the transient reflectivity oscillations relates to the lifetime of optical phonons. The lifetime is the inverse rate of the decay of optical phonons into two acoustic phonons. This lifetime also indicates the approach to the vibration instability (catastrophe) threshold...[Show more]
