Supercontinuum Induced by Filamentation of Bessel-Gaussian and Laguerre-Gaussian Beams in Water
Applied Sciences, 2022 In this paper, we study the characteristics of the supercontinuum (SC) induced by the filamentation of two typical vortex beams (i.e., Laguerre-Gaussian (LG) and Bessel-Gaussian (BG) beams) in water.

Coherent, directional supercontinuum generation
Optics Letters, 2017 We demonstrate a novel approach to producing coherent, directional supercontinuum and cascaded dispersive waves using dispersion engineering in waveguides. By pumping in the normal group-velocity dispersion (GVD) regime, with two zero-GVD points to one side of the pump, pulse compression of the first dispersive wave generated in the anomalous GVD ...

1.6-Octave Coherent OAM Supercontinuum Generation in As2S3 Photonic Crystal Fiber
IEEE Access, 2020 We design and simulate an all-normal dispersion arsenic trisulfide (As2S3) photonic crystal fiber (PCF) with high nonlinearity to enable a flat and coherent orbital angular momentum (OAM) supercontinuum (SC) generation.

Multi-octave supercontinuum generation from mid-infrared filamentation in a bulk crystal
EPJ Web of Conferences, 2013 We present supercontinuum generation pumped by femtosecond mid-infrared pulses in a bulk homogeneous material. The spectrum extends from 450 nm into the midinfrared, and carries high spectral energy density (3 pJ/nm–10 nJ/nm). The supercontinuum has high

Supercontinuum generation in scintillator crystals. [PDF]
Sci RepAbstractWe present a comparative experimental study of supercontinuum generation in undoped scintillator crystals: bismuth germanate (BGO), yttrium orthosilicate (YSO), lutetium oxyorthosilicate (LSO), lutetium yttrium oxyorthosilicate (LYSO) and gadolinium gallium garnet (GGG), pumped by 180 fs fundamental harmonic pulses of an amplified Yb:KGW laser.

Noise Fingerprints of Fiber Supercontinuum Sources [PDF]
, 2021 We present a novel technique for measuring unique ”noise fingerprints” of fiber supercontinuum (SC) sources, revealing a strong dependence of SC relative intensity noise not only on the dispersion of the fiber, but also on its cross-sectional ...
