Transient hole burning in the impurity crystals is studied by stochastic laser-dependent dephasing theory using the two random telegraph processes model for the frequency fluctuations.

We demonstrate laser frequency stabilization using a continuously regenerated transient spectral hole in an inhomogeneously broadened resonance of a solid. Regenerative transient holes provide extreme stabilization for time scales appropriate for spectroscopy, signal processing, ranging, and interferometry. Stabilization to 20 Hz on a 10-ms time scale using spectral holes at 793 nm in ${\mathrm{Tm}}^{3+}{:\mathrm{Y}}_{3}{\mathrm{Al}}_{5}{\mathrm{O}}_{12}$ gives substantial improvement in the reliability of stimulated photon echoes in the same material and enables the observation of a third population storage mechanism for hole burning in ${\mathrm{Tm}}^{3+}{:\mathrm{Y}}_{3}{\mathrm{Al}}_{5}{\mathrm{O}}_{12}.$

Spectral hole burning (SHB) allows to extend conventional spatial-domain optical data storage and coherent processing into the dimensions of frequency and time. To achieve ultrafast performance, on the time scale of 10-12 - 10-13s, we use organic dye-doped polymer materials at liquid-helium temperature. These materials enable SHB recording and coherent transient responses with a broad optical band width of 5 - 10 THz. We discuss applications of organic SHB systems for associative recall of time-and-space domain events, spectral programming of pulse trains, Stark switching of holograms, THz-bit-rate multiplication, cross- spectral processing and photon gated recording of erasure resistant coherent transients.
