Abstract
A theory of dual pump-probe spectroscopy is developed. At time t appro ximate to 0 the medium is subjected to two pulses with different carri er frequencies omega L and omega S. Then the same sample is probed by two pulses, omega L and omega S, after a delay time t(d). The transmis sion lineshape is explored as a function of t(d). Time resolution duri ng one period of the medium vibration can be achieved. The limitation on the pulse duration t(p) is determined by the dephasing time T-2:t(p )<<T-2.
