Study on Multi-wavelength Conversion of Stimulated Raman Scattering Based on Hydrogen-Methane Mixtures filled Anti-Resonant Hollow-Core Fiber

This work successfully demonstrates that by regulating the H ₂/CH ₄ mixed gas in a single anti resonant hollow fiber, multi wavelength Raman conversion from 1 μ m to 2.8 μ m and 4.3 μ m can be achieved in a single integrated structure, providing a novel and feasible technical approach for the development of compact multi wavelength mid infrared gas Raman lasers. The dataset displays the spectral data and 4um power measurement data collected by the AR-HCF tail end through a spectrometer at different pressures and mixed gas ratios during the experimental process.
