An experimental investigation of the temporal dynamics of a diode laser subject to optical feedback from an external cavity containing a cell filled with cesium vapor has been performed. Peculiar dynamic regimes, such as self-pulsing, low-dimensional, and high-dimensional chaos, characterized by a new time scale, much longer than the time scales of all instabilities taking place in diode lasers under standard feedback conditions, have been identified.
