我们演示了通过干涉两个不同腰的基本高斯光束而产生的光瓶光束陷阱。光束来自一个单一的激光源，使用一个马赫-曾德尔干涉仪，其臂具有不等的放大倍数。来自马赫-曾德尔的两束光的相消干涉导致了两束光在相互聚焦处的三维强度零。我们演示了在蓝失谐瓶束阱中捕获冷铯原子。(C) 2009年美国光学学会
We demonstrate an optical bottle beam trap created by interfering two fundamental Gaussian beams with different waists. The beams are derived from a single laser source using a Mach-Zehnder interferometer whose arms have unequal magnifications. Destructive interference of the two beams from the Mach-Zehnder leads to a three-dimensional intensity null at the mutual focus of the beams. We demonstrate trapping of cold cesium atoms in a blue detuned bottle beam trap. (C) 2009 Optical Society of America
