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 …

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

Over the past four years, there has been a surge of activity in the supercontinuum field since
the introduction of various types of microstructure fibers. The main reason for this great …

The state of the art of investigations on filamentation of a high-power femtosecond laser
radiation in transparent media is reviewed. The physical picture of this phenomenon is …

We present a technique for rapid characterization of degenerate nonlinear absorption and
refraction spectra using a femtosecond white-light continuum (WLC) pulse to perform Z …

We use a white-light continuum (WLC) Z-scan technique to measure the degenerate two-
photon absorption spectrum and associated dispersion of the nonlinear refraction in ZnSe …

We experimentally investigate the spectral extent and spectral profile of the supercontinuum
(SC) generated in transparent solids: barium fluoride, calcium fluoride, and fused silica upon …

We report the results of a systematic study of white light generation in different high band-
gap optical media (BaF 2, acrylic, water and BK-7 glass) using ultrashort (45 fs) laser pulses …

We reported that depressed cladding waveguides were successfully fabricated in the
sapphire crystal using a femtosecond laser. In waveguides and bulk sapphire, experimental …

We report the results of a study of white light generation in a 7.5 cm long crystal of a high
band-gap material, barium fluoride, using ultrashort (< 42 fs) laser pulses over a range of …
