Supercontinuum generation in a microstructured optical fiber by picosecond self Q-switched mode-locked Nd : GdVO4 laser

Abstract

An effective supercontinuum (SC) generation is demonstrated by injecting picosecond self Q-switched mode-locked Nd:GdVO4 laser pulses into a 1-m long microstructured fiber. The laser is operated at wavelength 100-nm, away from the longer zero-dispersion of this dual zero-dispersion wavelength microstructured fiber., The phenomena of modulation, instability, stimulated Raman effect, and dispersive wave can be sequentially observed from experimental results, leading to spectral broadening as pumping increases.
