Supercontinuum Generation In Optical Fibres
In this work, a high power Ytterbium pump laser was used in a quasicontinuous wave (CW) pump scheme to generate supercontinua in two different optical fibres, a depressed cladding, graded index highly nonlinear fibre (HNLF), and a solid core photonic crystal fibre (PCF). Pumping a 300 m length of the HNLF with a peak pump power of 140 W, a continuum with a spectral flatness of 5 dB over 1000 nm...

متن کاملCoherent fiber supercontinuum for biophotonics.
Biophotonics and nonlinear fiber optics have traditionally been two independent fields. Since the discovery of fiber-based supercontinuum generation in 1999, biophotonics applications employing incoherent light have experienced a large impact from nonlinear fiber optics, primarily because of the access to a wide range of wavelengths and a uniform spatial profile afforded by fiber supercontinuum...
متن کاملSupercontinuum generation with optical vortices.
We employ an optical vortex beam for the generation of femtosecond supercontinuum in a solid state medium. We demonstrate that the continuum generation process is initiated by the filamentation of the vortex, resulting in a spatially divergent continuum. Despite the strong self-focusing and the formation of multiple hot-spots along the vortex ring, the singularity is preserved in both the near-...
متن کاملutilizing intense supercontinuum light source
Combining the molecular specificity of the infrared spectral region with high resolution microscopy has been pursued by researchers for decades. Here we demonstrate infrared supercontinuum radiated from an optical fiber as a promising new light source for infrared microspectroscopy. The supercontinuum light source has a high brightness and spans the infrared region from 1400 nm to 4000 nm. This...
