Abstract

Experimental data on long-lived stimulated photon echo and photochemical spectral hole burning which cannot be explained by means of stochastic spectral diffusion (SD) theory are discussed. They are explained with the help of the dynamical SD theory developed recently.

Photochemical hole burning in polymers

Shinjiro Machida, Kazuyuki Horie

Photochemical hole burning in polymer systems are reviewed. Hie general concept of photochemical hole burning (PHB) is introduced and the types of photoreaction leading to PHB are outlined. Recent topics of PHB, namely, high-temperature hole burning, photon-gated hole burning, and possibility of applicating PHB to an optical device are presented. Single molecule spectroscopy and photon echo are briefly introduced.

High-Yield Picosecond Photon Echoes by Photochemical Hole-Burning

Rein K. Kaarli, Alexander Rebane, Peeter Saari

The phenomenon of stimulated photon echo [1] has already been investigated in a variety of molecular systems but in all cases the magnitude of echo signals has been limited to a small fraction of the pumping pulses intensity. The main reason for that lies in a rapid relaxation of nonequilibrium population of molecular states, which hinder the formation of spectral population gratings responsible for the stimulation of retarded optical pulses.

Low temperature dynamics in amorphous solids: A photon echo study

Hans C. Meijers, Douwe A. Wiersma

The long-lived stimulated photon echo is put forward as a powerful technique to probe structural dynamics in glasses and other amorphous solids. We present results of optical dephasing measurements on several doped organic glasses (deuterated ethanol, toluene, and triethylamine) and polymers (polystyrene, polyvinylbutyral, and polymethylmethacrylate). Using a stochastic analysis within the so-called two-level-system model, we can extract from these measurements the distribution function of fluctuation rates over a huge range of time scales, varying from picoseconds to hundreds of milliseconds. We show that the dynamics, which lies at the origin of spectral diffusion, is very dependent on the glass structure and can be described by two separate hyperbolic distribution functions of fluctuation rates. From longitudinal photon echo measurements in the population dimension, we find evidence for structural dynamics which is not accounted for in the standard two-level-system model and which is related to a spatially inhomogeneous distribution of fluctuation centers.

Photochemical hole burning in rigidly coupled polyacenes

The process of photochemical hole burning in rigidly coupled polyacenes is discussed. Photochemical mechanisms in these systems are conducive to low temperature spectral hole burning. Several factors which determine the shape and width of spectral holes are discussed. Prospects for use in information storage applications are presented.
