Resumen
In this paper, we demonstrate novel properties in the phenomenology of supercontinuum generation in sapphire
with diffractive lenses and provide a complete spatial, spectral, and temporal characterization of the so-generated
pulses. Filament formation inside the sample is analyzed and related to the measured spectra, finding that clipping
of the filament results in blueshifted spectra. For comparison, filament formation with refractive lenses is also
examined, and the roles of diffraction and extension of the focusing region are inspected. The tunability achieved
in the anti-Stokes side of the spectrum is also extended to the ultraviolet by frequency mixing with infrared
femtosecond pulses.
