光学腔内集体发射诱导冷却的观测

Observation of Collective-Emission-Induced Cooling inside an Optical Cavity

Hilton W. Chan, Adam T. Black, Vladan Vuletic

摘要:

我们报告的集体发射引起的,速度依赖的光力的观察。一个由水平驻波照射的含有3 × 10^6个铯原子的下落样品的三分之一,通过向垂直取向的共焦谐振腔中协同发射光而停止。我们观测到的减速速度高达1500 m/s^2,冷却温度低至7 uK,远低于自由空间多普勒极限。测得的力大大超过了预测的一个单一的二能级原子。

英文摘要:

We report the observation of collective-emission-induced, velocity-dependent light forces. One third of a falling sample containing 3 x 10^6 cesium atoms illuminated by a horizontal standing wave is stopped by cooperatively emitting light into a vertically oriented confocal resonator. We observe decelerations up to 1500 m/s^2 and cooling to temperatures as low as 7 uK, well below the free space Doppler limit. The measured forces substantially exceed those predicted for a single two-level atom.
