Theory of One- and Two-Step Pulsed 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).

The Shape of a Spectral Hole and Its Temporal Response at Short Burning Times in Two‐, Three,‐ and Four‐Level Systems

Inna Rebane

Abstract The shape of the spectral hole in an inhomogeneous distribution function of centres over the transition frequency is calculated for the case of a quasimonochromatic burning light pulse which characteristic duration time is comparable to the relaxation times of the excited electronic level. Two‐step spectral hole‐burning in the cases of three‐ and four‐level systems as well as one‐step processes are considered. The temporal responses of the spectral holes as spectral filters on δ‐pulse of light are found.

Theory of Two‐Step Spectral Hole Burning by Pulses

Inna Rebane

Abstract A two‐step spectral hole burning (SHB) is considered, where the selective excitation of the first step is fixed by a photochemical transformation through the second excitation step. It is shown that in a three‐level system excited by two consecutive pulses, the kinetics of the forming spectral hole differs essentially from the one on stationary irradiation. In the case of a short second pulse the shape of the hole in the inhomogeneous distribution function (IDF) of the purely electronic line frequency Ω01 is dependent on the time interval T between the first and second excitation steps and under certain conditions a hole can be obtained which is narrower than in the one‐step SHB with monochromatic light. It is considered how the hole in IDF is manifested in the absorption and two‐step pulse excitation spectra. It is shown that the hole in the absorption spectrum may be narrower than 2γ1 and in the two‐step pulse excitation, −γ1 (γ1 is the energy relaxation constant of the first excited level).
