Open publisher page 1 citations

Abstract

We have laser collimated a chromium atomic beam in one dimension using the Doppler laser cooling technique.The experimental setup was given,in which,the laser was tuned 5MHz below the chromium transition by an AOM,the laser was generated by a frequency-doubled single-mode Ti:Sapphire laser.We also modulated the results of cooling.By calculating,the angular divergence of the atomic beam was reduced from 4.5mrad to 0.9mrad.
