Size-dependent high-order harmonic generation in rare-gas clusters.
High-order harmonic generation (HHG) is investigated in rare-gas clusters as a function of the cluster size using 0.8 and 1.3 μm femtosecond lasers. A characteristic, species-dependent knee structure in the single particle response is observed. A 1D recollision model qualitatively reproduces this behavior and associates it to the degree of delocalization of the initial wave function. Small clu...
متن کاملHigh-order harmonic generation in atom clusters.
We report the generation of short-wavelength, high-order harmonics of intense laser radiation from atom clusters. Clusters containing about 10 3 atoms are produced in a high-pressure gas jet. We show them to be a unique nonlinear medium. Compared with monomer gases they yield a higher appearance intensity for a given harmonic order, stronger nonlinear dependence of harmonic signal on laser inte...
متن کاملGas jet structure influence on high harmonic generation.
Gas jets used as sources for high harmonic generation (HHG) have a complex three-dimensional density and velocity profile. This paper describes how the profile influences the generation of extreme-UV light. As the position of the laser focus is varied along the jet flow axis, we show that the intensity of the output radiation varies by approximately three times, with the highest flux being obse...
متن کاملStructure and dynamics of noble gas-halogen and noble gas ionic clusters: When theory meets experiment
As part of this special issue in honor of Gerardo Delgado Barrio, we have reviewed the interplay between experimental and theoretical work on halogen and interhalogen diatomic molecule bonded to one or more noble gas atoms and also ionic clusters consisting of noble gas atoms. Although the Madrid group has worked on many theoretical issues, they have made particularly important contributions to...
متن کاملHigh harmonic generation in Ne and H2 gas mixtures
High harmonic generation (HHG) enables the production of coherent light in the extreme-ultraviolet (XUV) spectral region. However, the radiation conversion efficiency from infrared to the XUV is low. We observed enhancement of HHG in gas mixtures ofH2 and Ne compared to pure gasesH2 or Ne. Our experiments show that at an intensity of ∼1.5 × 1014 W∕cm2 and in mixtures of gases with significantly...
