Abstract
We report the results of the first experiment on recording of photon echo and self-diffraction signals in a zinc oxide semiconductor film of nanoscale thickness, which are excited by two-photon absorption of femtosecond laser pulses with wavelengths of 800 to 840nm for the exciton transition at room temperature.
