A colliding microjet liquid sheet target system was developed and tested for pairs of round nozzles of 10, 11 and 18 μm in diameter. The sheet’s position stability was found to be better than a few micrometers. Upon interaction with 50 mJ laser pu

Ultrashort laser pulses are widely used for the precise structuring of semiconductors like silicon (Si). We present here, for the first time, a comparative study of experimentally obtained and numerically simulated two-dimensional ablation profiles b

Focussing of the output beam of optical fibers is required in a variety of applications. We present a laser micro-machining technique for the fabrication of micro-lenses directly on the end face of single-mode silica fibers using a F2-laser processin

A deep ultraviolet F2 laser, with output at 157-nm wavelength, has been adopted for micro-shaping the end facets of single and multi-mode silica optical fibres. The high energy 7.9-eV photons drive strong interactions in the wide-bandgap silica fibre

Polarized second-harmonic generation (SHG) coverage dependencies for alkali (Na, Li) adsorption on Si(111) 7 × 7 both at room and at low temperatures are obtained for fundamental wavelengths of 497 nm, 570 nm and 1067 nm, showing characteristic and

Applying the combination of a solid-state Ti:Sa laser system and a newly developed wide-aperture, discharge-pumped KrF amplifier, output pulses with over 9 W average power at 300 Hz have been achieved in a single output beam. The frequency-tripled se

A new scheme to increase the extractable energy from a table-top KrF amplifier up to 100 mJ/pulse is presented. Applications of such pulses for micro-machining and for the generation of powerful XUV radiation are demonstrated.

Optical second-harmonic generation (SHG) is studied for the confined geometry of a circular cylindrical waveguide or optical fiber. A model situation of high symmetry is considered where the material with nonlinear susceptibility is isotropic and dis

Resonantly enhanced optical second harmonic generation at a pump laser energy of 1.17 eV was applied to investigate the Na-adsorption process on the 7×7 reconstructed Si(1 1 1) surface at room temperature. The change of second harmonic (SH) intensit
