利用脉冲塞曼不平衡辐射压技术，从磁光阱中引出冷铷原子束。我们观察到分离的原子束的速度尺度与双光子亚多普勒共振的辐射压力力，并表明，实验观察是在很好的协议与理论预测。我们发现，在最佳条件下，由均匀磁场提取的原子束的纵向温度在12 char 21 {}30 ensuremath{mu}mathrm{K}的区域内，这是一个数量级低于迄今为止获得的温度与磁方案。
We extract a cold rubidium 85 atomic beam from a magneto-optical trap using the technique based on the pulsed Zeeman-imbalanced radiation pressure. We observe the separation of an atomic beam on a velocity scale associated with the two-photon sub-Doppler resonances in the radiation pressure force, and show that experimental observations are in good agreement with theoretical predictions. We find that under optimal conditions an atomic beam extracted by a homogeneous magnetic field has a longitudinal temperature in a region of $12char21{}30 ensuremath{mu}mathrm{K},$ which is an order of magnitude lower than the temperatures obtained so far with the magnetic scheme.
