A review of studies of high-order harmonic generation in plasma plumes is presented. The
generation of high-order harmonics (up to the 101st order, λ= 7.9 nm) of Ti: sapphire laser …

High-order harmonics generation (HHG) in laser-induced plasmas is an advanced method
for creating coherent radiation sources in the extreme ultraviolet region for different …

The methods of enhancement of the strong high-order harmonics of femtosecond pulses in
laser-induced plasma are demonstrated. It comprises the application of the four techniques …

In recent years high-order harmonic generation (HG) has become one of the major topics of
super-intense laser-atom physics. Generally speaking, high harmonics are generated when …

We report the demonstration of strong resonance enhancement of a single high-order
harmonic in the extreme ultraviolet (XUV) region generated from the interaction of a …

We demonstrate the generation of very high-order harmonics, up to 250 eV, using argon
gas. This extends by 100 eV the highest harmonics previously observed using Ar and …

Detailed time-and space-resolved electron density measurements are presented for laser-
produced plasma waveguides. A density depression suitable for optical guiding begins to …

We report the studies of the generation of up to the 57th harmonic (λ= 13.96 nm) of a Ti:
sapphire laser radiation from the prepulse produced silver plasma. The plateau pattern …

When the radiation pulse of an intense laser propagates in gas, the atoms of the gas emit
odd harmonics of incident radiation. If λ is the incident wavelength, the outgoing radiation …

A review of CARS evolution from proof-of-the principle experiments to recent CARS
developments, including femtosecond CARS and higher order wave-mixing spectroscopy …
