摘要

We demonstrate a high-efficiency,high-power-nanosecond fiber laser-pumped broadband mid-infrared output based on a linearly chirped PPMgLN crystal.By using a linearly polarized pulsed Yb-doped fiber laser as the pump,we experimentally obtain a 1.22-W broadband mid-infrared laser output under pump power of 10.15 W.The 3-dB bandwidths of the idler and signal output are approxiwately 150 and 13 nm,centering at 3.60 and 1.51 μm,respectively.The measured idler spectrum shows a smooth spectral profile.
