Parallel to the rising of a number of scientific and industrial applications of ultrashort laser pulses, their precise temporal characterization has become a major issue. Recently, the new pulse measurement technique of dispersion-scan (d-scan) was introduced, which is based on measuring the spectrum of a nonlinear signal as a function of varying amounts of known dispersion added to the pulse [1]...
When a high-power infrared femtosecond pulse is focused into a transparent solid, different non-linear effects such as self-phase modulation, self-steepening, plasma generation or filamentation take place. These effects usually give rise to an extreme spectral broadening of the pulse that is termed supercontinuum (SC) generation [1]. In this contribution we demonstrate the possibility to tailor the...
The spatio-temporal characterization of the electric field of an ultrashort laser pulse after passing through a diffractive optical element has been done. The expressions derived for the total diffraction field in the time and spectral domain are validated using spatially resolved spectral interferometry assisted by an optical fiber coupler (STARFISH).
We make a review of the high harmonic generation (HHG) process, its characteristics and properties, presenting our main results in the field. The HHG is a very interesting source on the deep ultraviolet region with high potential in applications such as time resolved measurements and high spatial resolution imaging
