Use of scattering cooling liquid in a solar Nd:YAG laser

Here we investigate a pumping scheme using a diffuse scattering medium around the laser rod to prevent light escaping from the sides, improving absorption while providing increased homogeneity due to scattering. Modelling using a custom ray tracing program predicts large improvements in absorption w...

Summary:Here we investigate a pumping scheme using a diffuse scattering medium around the laser rod to prevent light escaping from the sides, improving absorption while providing increased homogeneity due to scattering. Modelling using a custom ray tracing program predicts large improvements in absorption when a scattering medium with high reflectivity is placed close to the crystal.
