Abstract
We describe a new effect, phonon-induced coherence loss (PICOLO), whereby a monoenergetic nonequilibrium phonon distribution is responsible for the loss of optical coherence. The interaction of these phonons with the ions is monitored with the free induction decay or photon echo. We show how PICOLO can be used to study the electron-phonon interaction and the dynamics of phonons.
