激光冷却俘获中性钠原子的实验研究
Study on Laser Cooling and Trapping Neutral Sodium Atoms
摘要
Abstract
We present a novel type of compact atomic source delivering cold sodium atoms with state-of-theart fluxes.Sodium atoms are firstly slowed down and captured in a two-dimensional magneto-optical trap (2D MOT),the cold sodium atom source in a 2D MOT thus realized represents a compact and convenient alternative to the classic one for loading a large number of atoms in a three-dimensional magneto-optical trap (3D MOT).We show how a shrewd choice of magnetic fields and the addition of a further laser beam results in higher yields of the atomic source.The results indicate that a description of the atomic source working principle with details of the vacuum system,optical,and magnetic setup.We achieve an atomic number exceeding 108atoms loaded in a 3D MOT.关键词
