Parametric generation in optical fibers in the 900-950nm spectral band

Abstract

An analysis of the parametric interaction and the initial fiber geometry to achieve wavelength conversion from common laser sources operating in the 1030-1064nm spectral band into the 900-950nm wavelength range has been performed. The preliminary analysis shows that new fiber designs involving fibers with cores engineered with crystal-like shapes and also pulsed fiber sources operating at wavelengths in the 1030-1064nm will be required to achieve efficient emission within the desired wavelength range. Both the fiber required for phase-matching the parametric nonlinear process and the pulsed fiber laser pump source are within reach of current technology. They both require engineering efforts to produce a packaged, rugged and compact source.
