High-energy broadband single-pass fibre Raman laser pumped by a cavity-taper output Nd?YAG laser

High-energy (0.68 mJ or 55 kW) broadband (0.38 to 2.22 μm) nonlinear optical conversion has been obtained in a conventional multimode optical fibre using a Nd: YAG pump laser with a direct optical fibre taper output and a taper-to-fibre coupling scheme. A taper-to-fibre launching efficiency exceeding 75% has been determined analytically and is compared with the experimental results.
