This paper introduces and discusses the main aspects of ultrashort laser pulse filamentation
in various transparent media such as air (gases), transparent solids and liquids. The …

We review supercontinuum generation in optical fibers for particular cases where the
nonlinear spectral broadening is induced by pump radiation from fiber-format sources …

We theoretically and experimentally investigate the mutual collapse dynamics of two
spatially separated optical beams in a Kerr medium. Depending on the initial power, beam …

By numerically solving the generalized nonlinear Schrödinger equation, we provide a
comparative analysis of spectral and temporal transformations of pico and femtosecond …

Evolution of the long-wavelength edge of supercontinuum (SC) in a large mode-area
photonic crystal fiber (LMA PCF) under extreme (close to the fiber damage threshold) …

It was assumed that primordial energy could be described as a wave function. A simulation
using parametric down conversion which increments the number of photons, but at a longer …

We suggest that supercontinuum can be used for absorption spectroscopy to observe the
exciton levels of a semiconductor nano-structure. Exciton absorption spectrum of a …

We experimentally probe molecular ionization and dissociation of methane molecules in the
gas phase upon their irradiation by intense pulses of white light that spans the wavelength …

Developing new optical imaging and spectroscopy techniques based on supercontinuum
(SC) light sources is the major theme of this thesis. As a complex nonlinear optical …

Due to the Kerr effect, high optical intensity in a medium (eg an optical fiber) causes a
nonlinear phase delay of the propagating light. That phase delay which has the same …
