Abstract First-principles simulations were conducted to explore various electronic properties of crystalline SiO2 (α-quartz) under ultrafast laser irradiation.

The editors of this book have succeeded admirably in bringing together the best work on materials processing at the nanometer scale. The sheer number of 1,245 pages, organized in three volumes and illustrated with 586 figures, shows how comprehensive it has become. It is the right book at the right time: ultrafast lasers (that is, lasers with ps and fs pulses) have become available with ever-higher average powers.

Abstract : The generation of an elliptical Bessel–Gauss beam has become a topic of interest in ultrafast laser processing of transparent materials because of its nearly non-diffractive elliptical central core. These beams can show potential in generating anisotropic structures down to the nanoscale and in producing asymmetries in the induced fields of thermo-mechanical constraints relevant for material structuring.
