论文摘要
我们提出了一个面向对象的计算机程序，用于模拟激光冷却物理的各个方面。我们的软件既既易于使用又适应，从而允许用户指定级别结构，磁场轮廓或激光束的几何形状，失调和强度。该程序包含三个用于原子运动的近似级别，适用于不同的机制，可根据身体状况提供计算和计算效率的交叉检查。我们通过重现众所周知的现象来测试该软件，例如抑制狂犬病，电磁诱导的透明度，刺激的拉曼绝热通道和光学糖蜜。我们还使用软件包来定量模拟后乘有限的磁光陷阱，例如在狭窄的$^1 $ s $ _0 \ rightarrow^3 $ p $ _1 $ _1 $ _1 $ _1 $ _1 $ sr和$^{87} $ sr中形成的陷阱。
We present a python object-oriented computer program for simulating various aspects of laser cooling physics. Our software is designed to be both easy to use and adaptable, allowing the user to specify the level structure, magnetic field profile, or the laser beams' geometry, detuning, and intensity. The program contains three levels of approximation for the motion of the atom, applicable in different regimes offering cross checks for calculations and computational efficiency depending on the physical situation. We test the software by reproducing well-known phenomena, such as damped Rabi flopping, electromagnetically induced transparency, stimulated Raman adiabatic passage, and optical molasses. We also use our software package to quantitatively simulate recoil-limited magneto-optical traps, like those formed on the narrow $^1$S$_0\rightarrow ^3$P$_1$ transition in $^{88}$Sr and $^{87}$Sr.
