提出了一种利用红失谐准连续半高斯激光束（SGB）对连续波分子束进行减速的方案。用蒙特-卡罗模拟方法研究了连续波氘代氨分子束减速的动力学过程。研究表明，采用功率为1.5kW、最大光阱深度为7.33mK的单台准连续SGB，可以获得相对平均动能损失约为10%、相对输出分子数大于90%的ND 3分子束。
We propose a promising scheme to decelerate a CW molecular beam by using a red-detuned quasi-cw semi-Gaussian laser beam (SGB). We study the dynamical process of the deceleration for a CW deuterated ammonia (ND3) molecular beam by Monte–Carlo simulation method. Our study shows that we can obtain a ND3 molecular beam with a relative average kinetic energy loss of about 10% and a relative output molecular number of more than 90% by using a single quasi-cw SGB with a power of 1.5kW and a maximum optical well depth of 7.33mK.
