摘要

分子(原子)平面反射镜作为重要的光学元件之一, 被广泛应用于分子(原子)囚禁、储存、导引等实验中; 但由于其仅能实现粒子纵向速度改变而在横向上没有聚焦作用, 从而导致了粒子容易发散. 以重氨(ND3)分子为例, 提出了一种结构简洁、紧凑的微型静电曲面反射镜, 通过理论计算并与Monte-Carlo模拟, 验证了其在改变分子运动方向的同时能够实现横向聚束, 进而大大增加反射分子数目. 因此, 该类反射镜可广泛用于分子操控与装载以及构成各类分子腔体等领域.

Abstract

As one of the most important optical instruments, molecular (atomic) reflecting mirrors have been broadly applied in experiments for trapping, loading, and guiding of molecules (atoms); however, given that the mirrors can only change the velocity of particles in the longitudinal direction, there is no focusing capability in the lateral direction and particles can subsequently diverge. Using ND3 as an example, we propose a compact micro electrostatic curved mirror to address this issue; we show via theoretical calculations and Monte-Carlo simulations that the proposed mirror can both direct a beam of molecules and achieve transverse bunching of molecules. This kind of reflecting mirror can be used in an extensive range of optical applications for manipulating or loading molecules, composing molecular cavities, and so forth.

Key words： micro electrostatic curved mirror; cold molecules; molecular cavity
