We demonstrate that accumulated photon echoes can be generated by synchrotron radiation. This is an experiment of a nonlinear optical effect carried out by using the radiation from an electron storage ring. A dye-doped polymer film was excited by the visible light from the storage ring, and the accumulated photon echoes from the sample were observed by employing a phase-modulation technique. The use of synchrotron radiation facilitates the extension of the spectral range where we can observe photon echoes with ultrahigh time resolution.
