Laser Collimation of a Chromium Beam



R E. Scholten, R Gupta, Jabez J. McClelland, Robert Celotta, M Levenson, M Vangel


We have studied laser collimation of a chromium atomic beam using a transverse polarization gradient cooling scheme. We present detailed measurements of the angular distribution of atoms on the beam axis, over a broad range of laser intensities and detunings including those which produce significant excitation, and observe collimation angles as small as 0.16 plus or minus} 0.01 mrad (50% quantile). We compare our results with existing calculations based on assumptions of steady-state conditions and low excited-state population.
