晶体中相干声子量子拍频的飞秒 TR －CARS研究
Theoretical investigations of quantum beats of coherent phonons in crystal by femtosecond TR-CARS
摘要
Abstract
A theoretical model of studying the dynamics of coherent phonons in crystals was established by femtosecond TR -CARS technique , and the quantum beats of the simultane-ously excited two phonon modes were imitated .The influence on the curves of quantum beats when altering the parameters of the wavenumber difference , the ratio of amplitude actor and the dephasing times of the two phonon modes were discussed .This paper put forward a theo-retical basis to study coherent phonon dynamics in crystals on a femtosecond time scale , and was especially helpful for understanding the nature of coherent phonons .关键词
