我们开发了一个原子光学系统，利用激光二极管（LD）的激光原子冷却和捕获。LD易于维护和操作，因此适合于工程应用。铬原子束经多普勒冷却准直后，经驻波透镜聚焦，直接沉积在硅衬底上。成功地实现了具有与驻波波长212.78 nm相同的周期性的纳米光栅结构。对原子束的产生、准直、聚焦和沉积过程进行了实验和理论研究。
We developed an atom-optical system that utilized a laser diode (LD) for both laser atom cooling and trapping. The LD is easy to maintain and operate, and is therefore suitable for engineering applications. The neutral atom beam of chromium was collimated by Doppler cooling and focused by a standing wave lens, and then directly deposited onto a silicon substrate. A nanograting structure with periodicity identical to the wavelength of the standing wave, 212.78 nm, was successfully achieved. The atom beam generation, collimating, focusing and deposition processes were experimentally and theoretically investigated.
