TLDR
Third-harmonic generation and three-wave sum-frequency light generation in a short-length elliptical-core optical fiber pumped by pulses from a Q-switched and mode-locked Nd:YAG laser, operating at 1.064microm, have been observed in the 355-385-nm spectral range.Abstract:
Third-harmonic generation and three-wave sum-frequency light generation in a short-length elliptical-core optical fiber pumped by pulses from a Q-switched and mode-locked Nd:YAG laser, operating at 1.064 μm, have been observed in the 355–385-nm spectral range. In particular, the third harmonics of the pump (λ0 = 1.064 μm, λ0/3 = 354.7 nm) and of the first Raman Stokes (λ1 = 1.116 μm λ0/3 = 372.0 nm) lines have been obtained with 5-kW peak power of the laser pulses.read more

Simultaneous generation of spectrally distinct third harmonics in a photonic crystal fiber

TL;DR: Frequency-resolved optical gating experiments combined with analysis and modal simulations suggest that the mechanism for the simultaneous generation of two visible radiation components is third-harmonic conversion of the fundamental pulse and its split Raman self-shifted component.

Analysis of frequency-doubling processes in optical fibers using Raman spectroscopy.
J. M. Gabriagues,H. Février +1 more
TL;DR: This work experimentally found a correlation between the nonlinear characteristics of frequency-doubling optical fibers and a specific modification of their Raman spectra and proposes a tentative interpretation of the physical origin of these phenomena, based on the assumption of the existence of small Si-O rings inside the fiber material.

TL;DR: In this article, the small signal Raman gain in a single-mode glass waveguide amplifier has been measured directly and the measured gain is in good agreement with that calculated from the Raman cross section.

Preservation of polarisation in optical-fibre waveguides with elliptical cores
TL;DR: In this paper, an analysis of the propagation characteristics shows that there is a point below the higher-mode cutoff where the difference in group velocities between the two fundamental modes is zero but where there is large enough difference in the phase velocity to preserve polarisation.

Phase-matched sum-frequency light generation in optical fibers
Y. Sasaki,Y. Ohmori +1 more
TL;DR: In this paper, phase matching was achieved by using the dispersion of the waveguide modes to compensate for bulk dispersion, achieving a conversion efficiency of 1.1×10−3 and 0.5×10 −3 from the pump into the two-wave sum-frequencies.

Sum-frequency light generation in optical fibers.
TL;DR: The generation in an optical-fiber waveguide of a spectral continuum spanning 29000 cm−1 from the near infrared to the ultraviolet is reported and an unexpected phenomenon is the generation of sum-frequency light derived from the pump frequency and the characteristic Raman Stokes frequencies of fused silica.
