Abstract

We report on time-resolved femtosecond photon echo experiments of a dye molecule in a polar solution. The photon echo is time resolved by mixing the echo with a femtosecond gate pulse in a nonlinear crystal. It is shown that the temporal profile of the photon echo allows separation of the homogeneous from the inhomogeneous contribution to the optical spectrum. A biexponential correlation function for frequency fluctuations is used to simulate the echo.
