Deceleration of a continuous-wave (CW) molecular beam with a single quasi-CW semi-Gaussian laser beam

We propose a promising scheme to decelerate a CW molecular beam by using a red-detuned quasi-cw semi-Gaussian laser beam (SGB). We study the dynamical process of the deceleration for a CW deuterated ammonia (NDoptical Stark deceleration, semi-Gaussian beamProject supported by the National Natural Science Foundation of China (Grant Nos 10374029, 10434060 and 10674047), the National Key Basic Research and Development Program of China (Grant No 2006CB921604), the Key Basic Program of Shanghai Municipality (Grant No 07JC14017), the Program for Changjiang Scholar and Innovative Research Team, and Shanghai Leading Academic Discipline Project (Grant No B408).3380P, 4260H6/1/2008 12:00:00 AMWe propose a promising scheme to decelerate a CW molecular beam by using a red-detuned quasi-cw semi-Gaussian laser beam (SGB).

We study the dynamical process of the deceleration for a CW deuterated ammonia (ND$_{3})$ molecular beam by Monte-Carlo simulation method. Our study shows that we can obtain a ND$_{3}$ molecular beam with a relative average kinetic energy loss of about 10{\%} and a relative output molecular number of more than 90{\%} by using a single quasi-cw SGB with a power of 1.5kW and a maximum optical well depth of 7.33mK.
