Abstract

Subpicosecond, picometer atomic displacements in &agr;-Te photoexcited by single femtosecond laser pulses have been measured by means of time-resolved optical reflectometry revealing threshold-like coherent quantum emission of single softened fully symmetrical optical A₁-phonons and demonstrating absolute detection capability of this technique in studies of coherent phonon dynamics in solids.
