- Аннотация: Efficient Raman laser based on the revolver hollow-core fibre (HCF) with a cladding formed by one layer of double nested capillaries was realized for the first time. Using hydrogen gas as a nonlinear medium we demonstrated single-pass single-stage 1064 nm–1907 nm Raman conversion with quantum efficiency as high as 40%. Improved mode confinement in the hollow core and low optical losses of the fibre enabled us to achieve Raman threshold as low as 270 W of peak power, which is 4–7 times improvement compared to previously reported results on 1.9 µm Raman generation in other types of HCFs. Further progress in revolver fibre technology could be a promising way to develop low-threshold, efficient, compact gas fibre lasers for various applications in the mid-infrared spectral range.
