Characterization of laser-induced ionization dynamics in solid dielectrics
Peter Jürgens, Benjamin Liewehr, Björn Kruse +8
The formation of an electron-hole plasma during the interaction of intense femtosecond laser pulses with transparent solids lies at the heart of femtosecond laser processing. Advan…
Plasma formation and relaxation dynamics in fused silica driven by femtosecond short-wavelength infrared laser pulses
P. Jürgens, M. J. J. Vrakking, R. Stoian +1
Laser-induced plasma formation and subsequent relaxation in solid dielectrics is the precursor to structural modifications that are accompanied by a permanent alteration of materia…
Origin of strong-field induced low-order harmonic generation in amorphous solids
P. Jürgens, B. Liewehr, B. Kruse +8
Kerr-type nonlinearities form the basis for our physical understanding of nonlinear optical phenomena in condensed matter, such as self-focusing, solitary waves, and wave mixing. I…
Single-step fabrication of surface waveguides in fused silica with few-cycle laser pulses
Federico J. Furch, W. Dieter Engel, Tobias Witting +2
Direct laser writing of surface waveguides with ultrashort pulses is a crucial achievement towards all-laser manufacturing of photonic integrated circuits sensitive to their enviro…
