1120 nm 窄线宽掺镱光纤激光器
Ytterbium-doped fiber laser at 1120nm with narrow linewidth
摘要
Abstract
In order to realize 1120 nm ytterbium-doped fiber laser with narrow linewidth , high power level , long wavelength (compared with 1030nm~1080nm), the resonator of fiber laser was composed of a normal single-mode Yb-doped fiber and a pair of fiber Bragg gratings (FBG).The theoretical-optimized active fiber length is used to ensure that pump light is entirely absorbed and nonlinear effect is suppressed .After theoretical analysis and experimental verification , the results show that when laser threshold pump power is 40mW and the launched pump power is 265mW, laser output signal power is up to 35mW with optical-to-optical conversion efficiency of 13.2%, central wavelength of 1120.9nm, output light linewidth of 0.03nm.The performances of the laser contribute to high reflectivity output coupler FBG , short cavity and low power operation .The laser can be injected into fiber amplifiers .关键词
