Nonlinear propagation of intense femtosecond laser pulses in bulk transparent media leads
to a specific propagation regime, termed femtosecond filamentation, which in turn produces …

Filamentation of ultra-short TW-class lasers recently opened new perspectives in
atmospheric research. Laser filaments are self-sustained light structures of 0.1–1 mm in …

The generation of power-and wavelength-scalable few optical cycle pulses remains one of
the major challenges in modern laser physics. Over the past decade, the development of …

Filamentation-assisted pulse compression in the gas phase is shown to enable the
generation of subterawatt few-cycle pulses in the mid-infrared (mid-IR). With both spatial …

We present spectral measurements that uncover the detailed dynamics of the
supercontinuum generation in fused silica, YAG, and LiF crystals when pumped with 100 fs …

We present a compact, uniform generalized Sellmeier-equation (GSE) description of air
refraction and its dispersion that remains highly accurate within an ultrabroad spectral range …

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 Keldysh photoionization theory is a conceptual cornerstone and a universal framework
for the description of a broad class of fundamental effects in light–matter interaction. Here …

We identify a physical scenario whereby optical-field waveforms with peak powers several
decades above the critical power of self-focusing can self-compress to subcycle pulse …

Precise control of the nonlinear optical phenomena is the limiting factor for the spectral
broadening and pulse compression techniques for high-power laser systems. Here we …
