Fibers are considered as extraordinary tabletop laboratories to investigate optical turbulence and optical rogue waves (ORW). However ultrafast measurement of random optical power fluctuations is a challenging experimental task and the typical sub-picosecond timescale prevented-up to now-time-resolved observations of the awaited dynamics. We report the first single-shot recordings of ORW emerging...
Laser Scanning Microscopy (LSM) techniques play in current days a key role in imaging and characterizing biological tissues. Among these, Multiphoton Microscopy (MPM), with its two main variants: Two-Photon Excitation Fluorescence (TPEF) and Second Harmonic Generation (SHG), has emerged as a powerful tool to investigate unprocessed tissues with resolution and detail comparable to standard histology...
Nonlinear optical (NLO) microscopy [1-3] allows for intrinsic confocal (three-dimensional) high-speed imaging with deep penetration and high molecular contrast. Two-photon excitation fluorescence (TPEF) has been widely employed in biological imaging, taking advantage of either the intrinsic fluorescence or the extrinsic labeling of cells and tissues. Coherent Raman scattering (CRS), comprising coherent...
