我们展示了一维磁光陷阱的极性自由基氢氧化钙(CaOH)。建立了一个类似于每个分子10(3)个光子的准闭合循环转变，主要受相互作用时间的限制。这使得能够在压缩分子束的同时对CaOH进行辐射激光冷却，导致轴上光束亮度显著增加，温度从8.4 MK降低到1.4 MK。
We demonstrate a 1D magneto-optical trap of the polar free radical calcium monohydroxide (CaOH). A quasiclosed cycling transition is established to scatter similar to 10(3) photons per molecule, predominantly limited by interaction time. This enables radiative laser cooling of CaOH while compressing the molecular beam, leading to a significant increase in on axis beam brightness and reduction in temperature from 8.4 to 1.4 mK.
