Ionization clamping in ultrafast optical breakdown of transparent solids
Anton Rudenko, Jerome V. Moloney, Pavel Polynkin
We formulate a multi-physics model to describe the nonlinear propagation of a femtosecond, near-infrared, tightly focused laser pulse in a transparent dielectric. The application o…
Universal threshold for femtosecond laser ablation with oblique illumination
Xiao-Long Liu, Weibo Cheng, Massimo Petrarca +1
We quantify the dependence of the single-shot ablation threshold on the angle of incidence and polarization of a femtosecond laser beam, for three dissimilar solid-state materials:…
Generation of multi-terawatt vortex laser beams
Craig Ament, Lee Johnson, Andreas Schmitt-Sody +3
We report the fabrication of large-area phase masks on thin fused-silica substrates that are suitable for shaping multi-terawatt femtosecond laser beams. We apply these phase masks…
Third and fifth harmonics generation by tightly focused femtosecond pulses at 2.2 μm wavelength in air
Gombojav O. Ariunbold, Pavel Polynkin, Jerome V. Moloney
We report experiments on the generation of third and fifth harmonics of millijoule-level, tightly focused, femtosecond laser pulses at 2.2 μm wavelength in air. The measured ratio…
Experimental Tests of the New Paradigm for Laser Filamentation in Gases
Pavel Polynkin, Miroslav Kolesik, Ewan M. Wright +1
Since their discovery in the mid-1990s, ultrafast laser filaments in gases have been described as products of a dynamic balance between Kerr self-focusing and defocusing by free el…
