Time and space domain holography by persistent spectral hole burning in photochemically active media is shown to permit storage, recall, and conjugation of temporal profiles of light signals as short as 100 fs. This limit for the temporal resolution is set by the finite spectral width of the impurity absorption bands of presently available recording materials.

    In this paper, we further evaluate a model for the analysis of Stark-shifted spectral holes, which allows for the determination of electric fields generated at the site of probe molecules by their host environment. In contrast to the conventional treatment of the Stark effect, our model regards...

    Holes burnt into the absorption spectrum of terrylene in hexadecane have quite unusual features: spectral diffusion behavior under thermal cycles shows a narrowing regime at very low temperatures (2–5 K) followed by a plateau region (up to about 13 K) and a broadening regime (T>13 K)....

    We have prepared sodium tellurite glasses doped with europium. Emission intensity of the europium-doped glass is at least 500× more than that of the undoped glass. Fluorescence features exhibited dependence on the pump laser wavelength. Persistent spectral hole burning was observed in the...
