摘要
构建了基于掺镱双包层光纤的超荧光种子源和放大器,实现了稳定运转的全光纤结构宽带超荧光光源,种子源经一级单程放大,获得百瓦级功率超荧光输出。该超荧光光源在高功率状态下无自脉冲、弛豫振荡、纵模起振。超荧光种子源中心波长1050 nm,半峰全宽(FWHM)21 nm,最大输出功率3 W。放大级超荧光最高输出功率102 W,斜率效率70%,FWHM 20.5 nm。
Abstract
Stable high-power operation of an all-fiber broadband superfluorescent source, based on ytterbium-doped double-cladding fibers, is achieved via a fiber amplifier. It comprises an amplified spontaneous emission (ASE) seed source which is amplified to over one hundred watts in the next stage for a single pass, with no self-pulsing, relaxation oscillation or lasing modes being observed. The center wavelength of ASE seed source is 1050 nm, and the full width half maximum (FWHM) is 21 nm. The maximum superfluorescent output power yielded by the amplifier is 102 W, the slope efficiency with respect to the pump power is 70%, and FWHM of the emission spectrum is 20.5 nm.
