Abstract

Abstract

The high or low coupling efficiency and the good or bad coupling facula directly affect the amplification effect of the Rod-type photonic crystal fiber. Therefore, it is necessary to research the coupling effect of seed light and choose a suitable laser as a seed source. In this paper, the coupling efficiency of Rod-type photonic crystal fibers in a solid-state laser and a fiber laser was theoretically analyzed. The changing regulation of the coupling efficiency and the effect of the alignment error on the coupling efficiency were calculated with two different lasers. A suitable lens or group of lenses were selected and an experiment was conducted to couple the solid-state laser beam and the fiber laser beam to the Rod-type photonic crystal fiber. Compared with the coupling effect of the two kinds of lasers, the maximum coupling efficiency of the solid laser is only 62.4%, while the coupling efficiency of the fiber laser is more than 80%. In the case of fiber laser coupling, the coupling efficiency at different power injection and the coupling facula were analyzed. The experimental results will guide the amplification experiment of the Rod-type photonic crystal fiber.
