Femtosecond Photon Echo In Solids: Selective Spectroscopy Not Using Zero-Phonon Lines
Игорь Сергеевич Осадько, M. V. Stashek
Fluorescence—line—narrowing, spectral hole—burning and single molecule spectroscopy are methods of selective spectroscopy using zero-phonon lines (ZPL) to make selection in molecular ensemble. However if electron-phonon coupling is strong or sample temperature is near to room temperature, ZPL are absent and the optical band consists of electron-phonon transitions which are called phonon-side-band (PSB). In these cases the above mentioned methods of selective spectroscopy do not work. Can we get an information concerning a homogeneous optical band from inhomogeneously broadened bands in these cases? The answer is yes if we use femtosecond photon echo.
