High-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...

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...

Observation of Cooper minimum in Krypton using high harmonic spectroscopy

High harmonic spectroscopy utilizes the methods of attosecond science to study electronic properties of atoms and molecules. We use a 1.8 μm 11 fs laser source to generate high harmonic spectra beyond 150 eV. The Cooper minimum in krypton is clearly visible in these spectra, and would otherwise be difficult to observe with 800 nm laser sources. We relate the shape of the spectrum to the photoio...

Deep-subwavelength waveguiding via inhomogeneous second-harmonic generation.

We theoretically investigate second-harmonic generation in extremely narrow, subwavelength semiconductor and dielectric waveguides. We discuss a guiding mechanism characterized by the inhibition of diffraction and the suppression of cutoff limits in the context of a light trapping phenomenon that sets in under conditions of general phase and group velocity mismatch between the fundamental and t...

Generation of High Order Harmonics from H2+ Molecule Ion by Using Homogenous and Inhomogeneous Laser Fields

We solved one dimensional Schrodinger equation in a H2+ molecular environment by using 3 femtosecond homogeneous and nonhomogeneous laser fields. In homogeneous case, we found out that larger inter nuclear distances result in earlier ionization and also more instability in the wave packet. We deducted that the more the instability is, the more modulated the power spectrum will be. So, by choosi...
