我们提出了一个一般的方案,用于在秒的时间尺度上将分子交感冷却到μK温度。从理论上估计了实验参数,表明了该方案的可行性。这种方法特别适合光学斯塔克减速,利用超冷、激光冷却的亚稳态稀有气体原子猝灭到其基态,作为碰撞伙伴,在深光学陷阱(150 mK)内共同捕获分子物种。我们还描述了测量的作用,激光诱导的分子排列在光学斯塔克减速的偶极力和轮廓进展走向实现啁啾光学斯塔克减速生产慢分子束与mK的能量扩散。
We propose a general scheme for sympathetic cooling of molecules to µK temperatures on a timescale of seconds. Experimental parameters have been estimated from theory, which indicate the viability of the scheme. This method, which is particularly suited to optical Stark deceleration, utilises ultracold, laser cooled metastable rare gas atoms quenched to their ground state as collision partners to co-trapped molecular species within a deep optical trap (150 mK). We also describe the measurement of the role of laser-induced molecular alignment on the dipole force in optical Stark deceleration and outline progress towards the realisation of chirped optical Stark deceleration for producing slow molecular beams with mK energy spreads.
