✦ Synopsis

It is reported about the first observation (in a
solid-state sample) and detailed investigation of the stimulated
femtosecond photon echo (SFPE) signals at room temperature in a
polyvinylbutural film doped with molecules of phthalocyanine of HW
1009 type at the wavelength of 788 nm. A dependence of relative
intensity of these echo-signals on time intervals between the
second and the third exciting pulses was studied and the SFPE
spectrum was investigated with respect to the spectra of both
exciting pulses and signals of self-diffraction. It was found that
the linear electron-phonon coupling is weak and the influence of
the phonon-side band of the absorption line on the SFPE signals is
less significantly than on the signals of primary photon echo.
