Abstract

The two-step persistent spectral hole burning (PSHB) of a hole in the inhomogeneous distribution function (IDF) of the optical transition frequencies in a three-level system by two successive light pulses, in the case of an exponentially increasing and decreasing first coherent pulse and an infinitely short second pulse is calculated. The compensation effect of the natural linewidth of the first excited level and the parameter describing the exponential decrease of the intensity of the first burning pulse is shown. The time-dependent zero-phonon line (ZPL) in luminescence spectrum in the recording scheme containing the time gate in front of the spectrometer with high resolution in the case of exponential opening and closing of the time gate is calculated. The effect of the compensation of the natural linewidth of the excited level and the parameter describing the exponential increase of the transparency of the time gate is shown.
