用于原子芯片的集成磁光阱特性

Characteristics of integrated magneto-optical traps for atom chips

S Pollock, J P Cotter, A Laliotis, F Ramirez-Martinez, E A Hinds

摘要:

我们研究了硅中微加工的金字塔形磁光阱(MOTs)的操作。的加载和损失率的测量提供洞察附近的表面在MOT动态的作用。荧光与激光频率和强度的研究使我们能够开发一个简单的操作理论。捕获在金字塔中的$^{85}$ Rb原子的数量大约为$L^6$,其中$L \lesssim 6$是以mm为单位的尺寸。这是从捕获速度和尺寸之间的关系很自然地得出的,并且不同于通常用于描述较大MOT的$L^{3.6}$。我们的研究结果构成了迈向完全集成的原子物理学实验和设备的实质性进展。

英文摘要:

We investigate the operation of pyramidal magneto-optical traps (MOTs) microfabricated in silicon. Measurements of the loading and loss rates give insight into the role of the nearby surface in the MOT dynamics. Studies of the fluorescence versus laser frequency and intensity allow us to develop a simple theory of operation. The number of $^{85}$Rb atoms trapped in the pyramid is approximately $L^6$, where $L \lesssim 6$ is the size in mm. This follows quite naturally from the relation between capture velocity and size and differs from the $L^{3.6}$ often used to describe larger MOTs. Our results constitute substantial progress towards fully integrated atomic physics experiments and devices.
