Supercontinuum generation is demonstrated in an on-chip silica spiral waveguide by launching 180 fs pulses from an optical parametric oscillator at the center wavelength of 1330 nm. With a coupled pulse energy of 2.17 nJ, the broadest spectrum in the fundamental TM mode extends from 936 to 1888 nm (162 THz) at -50  dB from peak. There is a good agreement between the measured spectrum and a simu...

We report a laser-diode-pumped 1407-nm Raman fiber laser with an output power of 1 W. In this three-cascaded cw Raman laser, based on a single active phosphorus-doped silica fiber, for the first time to the authors' knowledge successive generation of Stokes components of essentially different frequency shifts (1330 and 490cm(-1)) has been realized. These Stokes components are associated with bo...

This article presents the linguistic description of Venetian version Tractatus de locis terre sancte, Latin travel chronicle to Holy Land written by Francesco Pipino from Bologna (1270-1330 ca.). The we propose is divided into phonetics and morphology, then followed some general considerations about described features an index with attested lexical onomastic entries.
