The system has its own style . the trapping beams can be independently adjustable and three double - passed circularly polarized cooling / trapping beams intersect at the center of mot . about 1 107 cesium atoms with equivalent temperature of ~ 270 k are successfully trapped in our vcmot 在每束冷却俘获光的光强约4 . 9mw cm ~ 2 、失谐量为- 10mhz 、轴向磁场梯度约11 . 6gauss cm的条件下得到的冷原子样品中典型的原子数约1 10 ~ 7个，温度约270 k左右。
