Ripple formation in various metals and super-hard tetrahedral amorphous carbon films in consequence of femtosecond laser irradiation
Manuel Pfeiffer,Andy Engel,Hagen Gruettner,Katja Guenther,Franka Marquardt,Guenter Reisse,Steffen Weissmantel +6 more
TL;DR: In this paper, it was shown that on smooth surfaces the ripple orientation is perpendicular to the electric field vector of the linearly polarized laser beam, and that ripple period decreases with decreasing laser wavelength and/or increasing angle of incidence of the laser beam on the substrate.

TL;DR: In this paper, the authors present a mask projection of femtosecond or picosecond laser beams onto a substrate surface, in which the laser beam (2) consisting of laser beam pulses is, at a location of the optical axis, formed to make laserbeam pulses with an expanded laser beam cross section or laser beam signals with a reduced laser beam signal cross section and said laser beam(2) has a homogeneous intensity distribution over the laserbeam cross section.

TL;DR: In this paper, a femtosecond and a picosecond laser beam is projected onto a substrate by means of a mask, and a field effect lens system and an imaging lens are arranged such that non-diffracted and diffracted components of laser beam of pulses transmitted through limiter (6) and mask (7) are directed into lens (10), forming an image having a predetermined aperture using a field-effect lens system (8) such that in a cross-section of said laser beam in the image formation plane, a reduced intensity distribution image formed by lim
