dc.description.abstractWe analyzed bichromatic and polychromatic stimulated forces for laser cooling and trapping of Yb atoms using only the narrow S-1(0) -> P-3(1) transition. 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%.en
dc.description.notesThis research was funded by Office of Naval Research Grant No. N000141712255. Some of the computing was performed on the Sherlock cluster at Stanford University. We would like to thank the Stanford Research Computing Center for providing computational resources and support. T.N. developed the PYTHON codes and simulations used in this work and analyzed the results. T.M.L. and N.R. derived equations for the bichromatic force calculations and developed an earlier computer model of the bichromatic force in MATLAB. L.H. supervised this research. T.N. wrote the manuscript with input from L.H.en
