We report about a novel kind of supercontinuum generation in a photonic crystal fibre in which the spectral broadening occurs only on the blue side of the pump wavelength. As a consequence a limit to the extent of the supercontinuum is set and thus a

We report a spectroscopic investigation of potassium–lithium–tantalate–niobate (KTN:Li) across its room-temperature ferroelectric phase transition, when the sample manifests a supercrystal phase. Reflection and transmission results indicate an

An innovative two-photon microscope exploiting a line-shaped illumination has been recently devised and then implemented. Such configuration allows to carry out a real-time detection by means of standard CCD cameras and is able to maintain the same r

We demonstrate second-harmonic generation (SHG) in a KTN:Li ferroelectric perovskite that manifests giant refraction (n ⪢ 1) [1] . When light is focused on the vortex or anti-vortex cores of an underlying ferroelectric super-crystal (SC) [2] , [3]

We perform redundant x-ray diffraction versus temperature experiments in bulk transparent KTN. We find a violation of the standard perovskite cubic-to-tetragonal symmetry breaking at the Curie point in the form of an orthorhombic cell distortion. The

We experimentally investigate the two-photon absorption cross sections and spectra of eosin and hematoxylin for applications in nonlinear microscopy. The experiments are carried out on pure samples of the two dyes in DI-water solvent with different c

We propose an innovative experimental approach to estimate the two-photon absorption (TPA) spectrum of a fluorescent material. Our method develops the standard indirect fluorescence-based method for the TPA measurement by employing a line-shaped exci

We present a novel technique for the measurement of two-photon absorption spectra. A line-shaped excitation beam generates a strong induced fluorescence signal that can be easily detected by an image sensor.

We present a novel two-photon microscope employing a line-scanning technique that allows image acquisition at a high rate. The resolution turns out to be comparable to the one of common point-scanning systems.
