✦ Synopsis

A theory of dual pump-probe spectroscopy is developed. At time t = 0 the medium is subjected to two pulses with different carrier frequencies o, and ws. Then the same sample is probed by two pulses, we and ws, after a delay time fd. The transmission lineshape is explored as a function of td. Time resolution during one period of the medium vibration can be achieved. The limitation on the pulse duration & is determined by the dephasing time T2: t, K Tz.
