Coulomb explosion (CE) is identified as the mechanism of ion ejection under low fluence ultrashort pulse laser ablation of crystalline ${\mathrm{Al}}_{2}{\mathrm{O}}_{3}.$ The ion momenta are equal during ``gentle'' ablation. This is explained by imp

Morphological and ion time-of-flight (TOF) investigations of the laser-induced sputtering of crystalline Al 2 O 3 (“sapphire”) at 800 nm have been carried out as a function of the laser fluence, pulse duration and the number of pulses per site. T

High resolution interference and intermodulated optogalvanic saturation spectroscopy has been applied for isotope shift (IS) studies in the ground-configuration 4f 12 6s 2 of ErI. For the isotope pairs170–166Er and168–166Er the results confirm a

Self-focusing of ps laser pulses (λ=790 nm) due to the nonlinear Kerr effect is shown to provide an easy and flexible method for producing bulk structures with dimensions on the order of 10 μm without damaging the entrance or exit surfaces of the m
