We present a two-species laser cooling apparatus capable of simultaneously collecting Rb and Hg atomic gases into a magneto-optical trap (MOT). The atomic sources, laser system, and vacuum set-up are described. While there is a loss of Rb atoms in the MOT due to photoionization by the Hg cooling laser, we show that it does not prevent simultaneous trapping of Rb and Hg. We also demonstrate interspecies collision-induced losses in the Rb-Hg system.
我们展示了一种双物种激光冷却装置，它能够同时将铷（Rb）和汞（Hg）原子气体收集到磁光阱（MOT）中。文中描述了原子源、激光系统和真空装置。虽然由于汞冷却激光的光电离作用，磁光阱中存在铷原子损失的情况，但我们表明这并不妨碍铷和汞的同时捕获。我们还证明了铷 - 汞系统中物种间碰撞导致的损失。
