Polarization dependent harmonic generation in microstructured fibers

Route to broadband blue-light generation in microstructured fibers.

We explore theoretically the possibility of generating broadband blue light by copropagating a short soliton pump pulse and a broader signal pulse in a microstructured fiber with a zero-dispersion wavelength located between the center wavelength of the pump and the signal pulses. We show that the unique properties of microstructured fibers should allow for broadening of the signal pulse's spect...

Supercontinuum generation in large mode-area microstructured fibers.

Supercontinuum generation in large mode-area microstructured fibers is demonstrated by launching into the fiber ns pulses from a passively Q-switched Nd:YAG laser. The special properties of these fibers open the way to compact, single-mode, high-power supercontinuum sources with a low divergence of the output beam. The nonlinear phenomena leading to the formation of the broad spectrum are also ...

Supercontinuum generation in microstructured fibers and novel optical measurement techniques

Recent Advances in Microstructured Fibers for Laser Delivery and Generation

We report recent advances in the development of fibers for the delivery and generation of both single-mode and heavily multimode laser beams as well as recent progress in fibers for supercontinuum generation in spectral regimes spanning the visible to mid-IR.

Even harmonic pulse train generation by cross-polarization-modulation seeded instability in optical fibers

We show that, by properly adjusting the relative state of polarization of the pump and of a weak modulation, with a frequency such that at least one of its even harmonics falls within the band of modulation instability, one obtains a fully modulated wave at the second or higher even harmonic of the initial modulation. An application of this principle to the generation of a 80-GHz optical pulse ...
