Dynamic localization and Bloch oscillations in the spectrum of a frequency mode-locked laser

Opt Lett. 2005 Apr 1;30(7):786-8. doi: 10.1364/ol.30.000786.

Abstract

It is shown that a frequency mode-locked laser with a sinusoidal sweep of modulation frequency around a mode-locking condition represents an ideal optical system for observing in the spectral domain the phenomena of dynamic localization and Bloch oscillations of electrons in an ideal solid placed in an external ac electric field.
