Abstract

A convenient and efficient technique for controlling exact focusing of several noncollinear laser beams into the same point of a luminescent sample is proposed for optical photon-echo spectroscopy and four-wave mixing experiments. The technique proposed is based on a confocal luminescence microscope equipped with a sensitive multichannel detector for visualizing samples with a large magnification. The high efficiency of the scheme developed is confirmed by experimental study of photon echo in a polymer film doped with luminescent dye molecules.

Time-resolved nonlinear microspectroscopy with Gaussian beams: Photon echo and spatially encoded coherence

Minhaeng Cho

We extend our theoretical framework for time-resolved nonlinear microspectroscopy [M. Cho, J. Chem. Phys. 162, 124201 (2025)] to coherent four-wave-mixing spectroscopy using paraxial Laguerre-Gaussian (LG) beams. Unlike pump-probe or transient absorption techniques, photon echo is highly sensitive to the spatial phase structure of LG beams. This sensitivity arises because coherence evolution in inhomogeneously broadened absorbers depends on the radial and azimuthal indices of the LG modes used in the write-and-read processes within the photon echo configuration. Recent advances in spatial light modulators, metasurfaces, and ultrafast laser techniques have significantly improved spatial and temporal control over quantum materials. These innovations enable new approaches to studying heterogeneous systems, developing multidimensional microspectroscopy, and exploring alternative quantum information storage methods. In this work, we investigate photon echo signals generated by LG beams and derive analytical expressions for rephasing and non-rephasing photon echoes. Our results reveal how beam parameters influence nonlinear spatiotemporal responses, capturing spatial variations in pulse amplitudes, phases, and inhomogeneity-induced dephasing and rephasing. We show that customized ultrafast pulses and structured spatial light fields can enhance the spatial separation of photon echo signals and increase the density of stored quantum information. This work advances nonlinear molecular spectroscopy and quantum information science by leveraging structured light fields and ultrafast optics.

Femtosecond photon echo and four-wave mixing in dye-doped polymer films, semiconductors and heterostructures

В. В. Самарцев, Vladimir S. Lobkov, Tatiana G. Mitrofanova

A review of femtosecond experiments on photon echo (PE) and four-wave mixing (FWM) performed at room temperature is presented. The Weiner–Ippen technique of FWM spectroscopy is demonstrated in dye-doped polymer films (such as polyvinilbutural doped with phthalocyanine), semiconductors (CdS) and heterostructures (GaAs/AlGaAs). The experimental setup used in these experiments is described. The dephasing times are estimated and the relaxation mechanisms are discussed.

Custom Made Optical Pulses for Photon Echo Spectroscopy

Maaike T.W. Milder

Nonlinear optical techniques are widely used to study energy transport in nanoscale objects. In particular photon echo spectroscopy can be used to determine if the energy transport is coherent or not. In this project a novel phase sensitive nonlinear technique is proposed. The main feature of this technique is the application of two phase-locked pulses. The relative phase and the delay between the two pulses is set electronically by a pulse shaper based on a spatial light modulator (SLM). The use of an SLM ensures phase stability. The proposed method is tested on a model system of solutions of the dye molecule DTTCI in ethylene glycol and acetonitrile. The obtained results demonstrated that the parameters from the experimental data agree with those from previous studies. Hence, the proposed technique can be further developed for energy transport studies.

Luminescent scanning confocal microscope modified for observation of arbitrarily oriented single quantum systems

Stepan Boichenko, Evgueni F. Martynovich

A modified distribution of the light field of an exciting laser radiation entering into the objective of a scanning confocal microscope is proposed, for which the focused beam in the course of scanning is capable of exciting all absorbing dipoles with arbitrary orientation at approximately the same efficiency. Calculations show that the ratio of maximum luminescence intensities for the most and least favorably oriented dipoles amounts to 47%. Analogous calculations have been performed for other distributions of the input light field and the excitation efficiency is compared to that of the proposed field.

WHAT ROLE CAN FOUR-WAVE MIXING TECHNIQUES PLAY IN COHERENT CONTROL?

Vadim V. Lozovoy, Emily J. Brown, Igor Pastirk +2 more

The role of four-wave mixing (FWM) techniques in coherent control is considered from the point of view of some of the most important developments in this field over the past years, namely multiphoton excitation, pump-dump methods, interference between coherent pulses, chirped laser pulses, and optimal control. FWM techniques provide a powerful platform for combining coherently multiple laser pulses. We explore the effectiveness of these techniques in controlling chemical reactions. The phase relationship between the pulses is maintained by detecting the signal in a phase-matching direction. The results presented show control over the observed dynamics from ground and excited state populations. The FWM signal results from the polarization of the sample following three different electric field interactions. The virtual echo sequence is achieved by the interactions of the sample with three consecutive electric fields characterized by exp[i(kx-w t)], exp[-i(kx-w t)] and exp[i(kx-w t)]. This sequence allows control over the observed ground or excited state dynamics. With the photon echo pulse sequence, characterized by interactions with exp[-i(kx-w t)], exp[i(kx-w t)], and exp[i(kx-w t)], we find that control of ground and excited state populations is not achieved.

Coherent optical spectroscopy of promising materials for solid-state optical processors

В. В. Самарцев

State of the art of optical coherent spectroscopy of doped solids that are promising as information carriers for optical processors is reviewed. Special attention is paid to optical echo spectroscopy of doped crystals classified as the Van-Vleck paramagnets where the long-lived stimulated echo is observed with the optical-memory time reaching several hours at low temperatures. Modern elaborations of optical echo processors based on this echo phenomenon are discussed. Physical principles of femtosecond echo spectroscopy and coherent four-wave mixing spectroscopy are formulated. The abilities of these methods in the diagnostics of fast processes at room temperature are illustrated using examples of a doped polymer films. The results of elaborations of a new branch of optical spectroscopy (biphoton spectroscopy) are also presented. The advantages and possible applications of this method are demonstrated using an example of two crystals (Er 3+ :YAG and Cr 3+ :Al 2 O 3 ).
