1	High absorption large-mode area step-index fiber for tandem-pumped high-brightnes shigh-power lasers显示文摘A short absorption length ytterbium(Yb)-doped large-mode area(LMA)fiber is presented as a step forward to mitigate the stern problem of nonlinear scatterings in a tandem pumping scheme adopted for high-power fiber laser.The short absorption length was realized by incorporating high Yb concentration in the fiber core.Furthermore,by replacing the inherent silica cladding with a Ge-doped cladding,we were able to obtain low core numerical aperture(NA)and negate the detrimental effect of index-raising by high Yb concentrations.This overcomes the long-standing limitation in step-index Yb-doped fibers(YDFs)where high cladding absorption inevitably results in high NA,thus hampering single-mode operation.We report an LMA(~575μm^2)YDF with NA of 0.04 and absorption of 27 dB/m at 976 nm both traits promote power scaling of single-mode tandem pumped fiber lasers.To our knowledge,this is the highest cladding absorption attained in a low-NA step-index fiber to date.An all-fiber tandem-pumped amplifier was built using only^14 m of the YDF.The amplifier delivered a near-Gaussian beam(M^i.27)at 836 W output power(pump power limited)with a high slope efficiency of^83%.Thanks to the short length and the tandem pumping,no indication of limiting factors such as stimulated Raman scattering,photodarkening,and transverse mode instability was observed.
