Near-diffraction-limited supercontinuum generation in a cladding-pumped nonlinear fiber converter

open access: yes
Through nonlinear scattering including stimulated Raman scattering and beam cleanup, a pulsed multimode pump beam is converted into a nearly diffraction-limited supercontinuum extending from 1 to 2 µm in a passive cladding-pumped nonlinear fiber ...

SUPERCONTINUUM GENERATION IN SPECIAL NONLINEAR PHOTONIC CRYSTAL FIBERS FOR NEAR INFRARED WAVELENGTHS

open access: yes, 2017
"In this work, we presented the nonlinear effects involved in our case in supercontinuum generation and we also tested seven different HNL PCFs. Then the results were analyzed to determine the best fiber and the key design factors.

Few-cycle fiber pulse compression and evolution of negative resonant radiation

open access: yes, 2014
We present experimental observations of the spectral expansion of fs-pulses compressing in optical fibers. Using the input pulse frequency chirp we are able to scan through the pulse compression spectra and observe in detail the emergence of negative ...

Photonic crystal fibres for coherent supercontinuum generation [PDF]

open access: yes, 2012
In this research photonic crystal fibres were developed for the purpose of generating coherent supercontinua. Two photonic crystal fibres were fabricated with all-normal group velocity dispersion profiles, with low dispersion at pump wavelengths 800 nm ...

RGB generation in secondary cores of microstructured fibres

open access: yes
Generation of white laser light in the visible regime currently attracts a lot of attention. Optical-fibre-based solutions have so far been presented by supercontinuum generation in tapered fibres and small-core microstructured holey fibres.
