Abstract

A model of an incident light passing through an optical waveguide with a hydrogen Raman medium with localized boundary conditions was constructed. A laser with a 532 nm wavelength for the laser pump, and H₂ Raman medium was used in the simulation. A ratio of 0.0074 for the beam waist and bore radius is found to produce the optimum conversion. A 27-fold increase was achieved when a 10.0 μm radius waveguide was added at 30 mJ input energy. This increase in the conversion efficiency can be attributed to the coupling of the numerical aperture and the radius of the waveguide.
