Our model is based on numerical solutions of optical Bloch equations for two-level atoms driven by multiple time-dependent fields combined with Monte Carlo simulations, which account for realistic experimental conditions such as atomic beam divergence, geometry, and Gaussian laser modes. Using 1 W of laser power, we predict a loading rate of 10(8) atoms/s into a 556-nm magneto-optical trap (MOT) with a slowing force of approximate to 60F(rad). We show that a square-wave modulation can produce similar stimulated forces with almost twice the velocity range and improve the MOT loading rate of Yb atoms by up to 70%.application/pdfenCreative Commons Attribution 4.0 Internationalpython frameworkbeamdynamicsforcequtipArticle - Refereedhttps://doi.org/10.1103/PhysRevA.104.05311710452469-9934
