摘要：
We demonstrate experimentally the complex and extensive spectro-temporal dynamics of stimulated Raman scat-tering in CO2-filled hollow-core photonic crystal fiber, pumped by a single infrared microchip laser; namely, the cascading transient Raman process and self-similar behaviors in the regime of higher-order Stokes wave generation. Our measurements are in good agreement with the numerical simulations based on the nonlinear Schrodinger equation. (c) 2023 Optica Publishing Group
