Spectral Hole-Burning

Inna Rebane

A theory of spectral hole burning (SHB) by light pulses of an arbitrary shape and duration is proposed. One- and two-step (photon-gated) SHB processes induced by laser pulses in two-, three- and four-level systems are theoretically considered. It is shown that for two-step SHB there exists a possibility of obtaining spectral holes which are narrower than in the one-step SHB with monochromatic light. In case of one- and two-step SHB the dependence of the shape of the hole on the duration of the burning pulse is considered (on two-step SHB the second pulse is Δ-pulse).

Spectral hole burning acting as a high resolution spectroscopic technique has potential applications on high density optical storage. The present paper report the research results on inhomogeneous broadening, fluorescence line narrowing, high temperature persistent spectral hole burning, mechanism of hole burning, hole burning dynamics and thermal stability of spectral holes. We designed and prepared new material system of divalent samarium ion doped alkaline earth metal fluoridehalides for high temperature hole burning. Room temperature hole burning and spectral hole with longer lifetime were performed. Various local configurations were distinguished by using time resolved spectroscopy. Spectral redistribution induced by hole burning indicates that trivalent samarium ions act as electron traps. Hole burning dynamics was analyzesed by using Block theory.

We propose a simple experimental approach to measure and quantify the polarization hole-burning in an optical amplifier. The spectral properties of polarization hole-burning are similar to those of spectral hole-burning
