摘要:
We have performed an experiment to optically cool and compress a thermal beam of sodium atoms by employing a two‐dimensional version of a magneto‐optical trap. The beam compressor employs a tapered transverse magnetic field gradient formed by four pairs of permanent magnets. We measure the efficiency of collimation and compression as function of longitudinal velocity group. ©1996 American Institute of Physics.
