Abstract

One of the most interesting recent developments in coherent laser spectroscopy on semiconductors is the introduction of quantum beat spectroscopy [1], which has been used for determining energy splittings, and measuring the dynamics of excitonic wavepackets. When two or more closely spaced optical transitions are simultaneously excited by a short (i.e. spectrally broad) laser pulse, interference phenomena will be observed during a time interval of the order of the dephasing time, which are generally referred to as quantum beats. These beats may be of quite different nature, depending on whether the transitions involved are independent, or are coupled with each other.
