Characterization of homoclinic chaos through double-valued return time maps
(1998) [Journal article]For a laser with a saturable absorber (LSA) and for a subnormal glow discharge (GD), both displaying homoclinic chaos, it is shown that double-valued curves in the return time maps, reconstructed from the time evolution ... -
Characterization of ultrashort pulses by a modified grating-eliminated no-nonsense observation of ultrafast incident laser light E fields (GRENOUILLE) method
(2005) [Journal article]The measurement and characterization of ultrashort laser pulses remains an arduous task. The most commonly used pulse-measurement method is known as frequency-resolved optical gating (FROG), and another version with great ... -
Light with tunable non-Markovian phase imprint
(2015) [Journal article]We introduce a simple and flexible method to generate spatially non-Markovian light with tunable coherence properties in one and two dimensions. The unusual behavior of this light is demonstrated experimentally by probing ... -
Molecular dynamics investigation with the time resolved optical Kerr effect on the CS2–C6H6 mixtures
(2006) [Journal article]An investigation of the molecular dynamics in pure liquids and in mixtures through the technique of time resolved optical Kerr effect is performed. The samples studied were the mixtures of carbon disulfide (CS2) with benzene ... -
Phase transformation of a vortex beam in a liquid-based inferior mirage
(2020) [Journal article]We study how a liquid-based inferior mirage, obtained by layering distilled water and ethanol, transforms the phase structure of a light beam possessing a helical wave front. An inferior mirage amounts for one total internal ... -
Pump-probe and pump-deplete-probe spectroscopies on carotenoids with N=9–15 conjugated bonds
(2006) [Journal article]A series of all-trans-carotenoids with N=9, 13, and 15 conjugated bonds has been studied by pump-probe and pump-deplete-probe spectroscopies to obtain a systematic analysis of the energy flow between the different electronic ... -
Study of nascent NaH in sodium-hydrogen mixture using resonant CARS and FWM processes
(1992) [Journal article]The Coherent anti-Stokes Raman Spectroscopy (CARS) technique was applied to measure the O Q, and S branches from the first, second and third overtones of the XICt ground state of NaH. Moreover, P and R doublets were also ... -
Super rogue wave generation in the linear regime
(2020) [Journal article]Extreme or rogue waves are large and unexpected waves appearing with higher probability than predicted by Gaussian statistics. Although their formation is explained by both linear and nonlinear wave propagation, nonlinearity ... -
Time-resolved optical Kerr-effect investigation on CS2/polystyrene mixtures
(2005) [Journal article]The relaxation dynamics of carbon disulfide are investigated in mixtures with polystyrene (PS) using the time-resolved optical heterodyne-detected optical Kerr effect (OHD-OKE). The data are analyzed using both the ... -
Topological model of homoclinic chaos in a glow discharge
(1995) [Journal article]We perform a topological analysis of homoclinic chaos in an experimental dynamical system: the glow discharge (GD). The geometrical model accounting for the stretching and folding mechanisms in the GD attractor is the ...
