Published in 2017 at "Physical Review A"

DOI: 10.1103/physreva.95.063802

Abstract: To date, investigations of carrier-envelope-phase (CEP) dependent effects have been limited to optical pulses with few cycles and high intensity, and have not been reported for other types of pulses. Optomechanical systems are shown to… read more here.
