We present a study of the possibility to significantly enhance the efficiency of high-order harmonic generation (HHG) using few-cycle optical waveforms obtained by superposing two laser pulses of different color delayed optimally relative to each oth

Here, we propose a novel approach to probing the field-free orientation dynamics of an ensemble of polar molecules. This approach implies the measurement of the THz signal produced in a molecular target exposed to an intense femtosecond laser pulse.

The generation of terahertz radiation at optical breakdown of air by two-color laser pulses composed of the first and second harmonics has been experimentally studied. A strong dependence of the optimal phase shift between the components of the two-c

Neural grafting is a potential strategy to help restore auditory function following loss of spiral ganglion cells. As a first step towards the reconstruction of a neural pathway from the cochlea to the brainstem, we have examined the survival of feta

Asymmetric photocurrent produced by ionizing laser pulses in a gas is known to be a highly efficient source of terahertz radiation. We examine the possibility of exploiting the asymmetry of the medium itself, rather than the properties of the laser f

Macroscopic quasi-dc currents produced in gases ionized by intense two-color laser fields are known as an efficient source of highly intense broadband terahertz pulses. Recent experimental and theoretical studies give conflicting results regarding th

Immature dorsal root ganglion (DRG) neurons have previously been shown to survive implantation to the cavity of extirpated adult native DRG, send axons via the dorsal root into the host spinal cord and make functional sypnatic connections. Regenerati

Epitaxial growth of semiconductors in real crystal substrates begins by two- and three-dimensional nucleation. It is necessary to take into account the nucleus–substrate boundary energy and substrate surface defects, as well as the misfit angle of

A theoretical analysis and an experimental investigation of nucleating epitaxial Ge and GaAs films under chemical transport conditions at homoepitaxy were made. Estimation of nucleation rate was made taking into account the differences of temperature
