Orientation-dependent high harmonic generation in ZnO
Tzveta Apostolova, Balint Kiss, Deborata Rajak +6
We theoretically and experimentally investigate orientation-dependent high-harmonic generation (HHG) in zinc oxide subjected to intense femtosecond mid-infrared (MIR) laser pulses.…
High-harmonic generation in zinc oxide subjected to intense mid-infrared femtosecond laser pulse
Boyan Obreshkov, Tzveta Apostolova
We theoretically investigate photo-excitation of electron-hole pairs and high harmonic generation in the bulk of zinc oxide (ZnO) subjected to intense femto-second laser pulses wit…
Tunable in situ Near-UV Pulses by Transient Plasmonic Resonance in Nanocomposites
Anton Husakou, Ihar Babushkin, Olga Fedotova +6
We propose a new concept for generation of ultrashort pulses based on transient plasmonic resonance in nanoparticle composites. Photoionization and free-carriers plasma change the…
Unified Model for a Nonlinear Pulse Propagation in Composites and Optimization of THz Generation
Anton Husakou, Olga Fedotova, Ryhor Rusetsky +6
We describe a unified numerical model which allows fast and accurate simulation of nonlinear light propagation in nanoparticle composites, including various effects such as group v…
Femtosecond optical breakdown in silicon
Tzveta Apostolova, Boyan Obreshkov
We investigate photoinization, energy deposition, plasma formation and the ultrafast optical breakdown in crystalline silicon irradiated by intense near-infrared laser pulses with…
Blueshift of high-order harmonic generation in crystalline silicon subjected to intense femtosecond near-infrared laser pulse
Boyan Obreshkov, Tzveta Apostolova
We present the generation of high order harmonics in crystalline silicon subjected to intense near-infrared 30fs laser pulse. The harmonic spectrum extends from the near infrared t…
