摘要：
我们分析了仅利用窄线宽 $^1S_0\ ightarrow^3P_1$ 跃迁对镱原子进行激光冷却与俘获的双色和多色受激辐射力。我们的模型基于对由多个含时场驱动的二能级原子光学布洛赫方程的数值求解，并结合蒙特卡罗模拟，该模拟考虑了实际实验条件，如原子束发散、几何构型和 Gaussian 激光模式。在使用 1 W 激光功率的条件下，我们预测以约 $60F_{rad}$ 的减速力将原子装载到 556 nm 磁光阱中的装载速率约为 $10^8$ atoms/s。我们证明方波调制可以产生类似的受激辐射力，且速度范围几乎扩大一倍，并将镱原子磁光阱的装载速率提高最多 70%。
英文摘要：
We analyzed bichromatic and polychromatic stimulated forces for laser cooling and trapping of Yb atoms using only the narrow $^1S_0\rightarrow^3P_1$ transition. Our model is based on numerical solutions of optical Bloch equations for two-level atoms driven by multiple time-dependent fields combined with Monte-Carlo simulations, which account for realistic experimental conditions such as atomic beam divergence, geometry, and Gaussian laser modes. Using 1 W of laser power, we predict a loading rate of $\approx 10^8$ atoms/s into a 556 nm MOT with a slowing force of $\approx 60F_{rad}$. We show that a square wave modulation can produce similar stimulated forces with almost twice the velocity range and improve the MOT loading rate of Yb atoms by up to 70%.
