The purpose of this article is to provide practical introduction into numerical modeling of
ultrashort optical pulses in extreme nonlinear regimes. The theoretic background section …

We report on strong backward stimulated emission at 337 nm in nitrogen gas pumped by
circularly polarized femtosecond laser pulses at 800 nm. A distinct dependence of the …

We report on the generation of ultrabroadband supercontinuum (SC) by filamentation of two
optical-cycle, carrier-envelope phase-stable pulses at 2 μm in fused silica, sapphire, CaF_2 …

Waveform-controlled terahertz (THz) radiation is of great importance due to its potential
application in THz sensing and coherent control of quantum systems. We demonstrated a …

The utilization of sub-100 fs pulses has attracted attention as an approach to further improve
the quality and precision of femtosecond laser microfabrication. However, when using such …

Laser filamentation overcomes diffraction over a highly extended distance, making itself a
powerful tool for long-range stand-off detection and light detection and ranging (LIDAR) …

The recent demonstration of electron vortex beams has opened up the new possibility of
studying orbital angular momentum (OAM) in the interaction between electron beams and …

We review recent developments in the field of femtosecond filamentation. In a first part, we
describe the physical effects contributing to induce filamentation during the propagation of …

We report on harmonic generation experiments and calculations in air to investigate the
theoretical prediction of Kolesik et al.[Opt. Lett. 35, 2550 (2010)] for testing the recently …

We report an experimental and numerical investigation of third-and fifth-harmonic
generation in a CaF 2 crystal with 20 fs (three-optical-cycle), 2 μ m driving pulses. The …
