我们提出了一个定量模型的磁光陷阱工作在窄的过渡，过渡线宽和反冲位移是可比的。我们结合联合收割机的光散射过程的量子处理与原子运动的蒙特-卡罗模拟。通过将我们的模型与锶中5s（2 1）S（0）-> 5s 5 p P-3（1）跃迁的实验进行比较，我们表明，它在很宽的操作条件下定量地再现了云的大小、位置、温度和动力学，而没有任何可调参数。我们还提出了一个扩展的模型，定量再现原子转移到一个远离共振偶极陷阱，突出其作为优化复杂的冷原子实验的工具。
We present a quantitative model for magneto-optical traps operating on narrow transitions, where the transition linewidth and the recoil shift are comparable. We combine a quantum treatment of the light scattering process with a Monte-Carlo simulation of the atomic motion. By comparing our model to an experiment operating on the 5s(2 1)S(0) -> 5s5p P-3(1) transition in strontium, we show that it quantitatively reproduces the cloud size, position, temperature and dynamics over a wide range of operating conditions, without any adjustable parameters. We also present an extension of the model that quantitatively reproduces the transfer of atoms into a far off-resonance dipole trap, highlighting its use as a tool for optimizing complex cold atom experiments.
