[Abstract]:In recent years, with the navigation, communication, Internet and other areas of high-precision clock demand more and more urgent. Aluminum quantum logic clock is one of the hotspots in the research of optical frequency standard. The aluminum ion cocooled by calcium ion was selected as the reference physical system of optical frequency standard in our laboratory, and a series of key technology research work of ion optical frequency standard was carried out. This article summarizes my master's work, the main content is divided into the following aspects: 1. An experimental device for ion generation using laser sputtering technology was built. This system is used to realize stable loading, cooling and detection of calcium ions. After optimizing the parameters of laser energy and RF power of laser sputtering experimental device, the time of single preparation of calcium ion was shortened from 10-20 minutes in atomic furnace to less than 10 seconds. 2. A bidirectional temperature control F-P reference cavity for narrow linewidth laser system is developed. The zero expansion coefficient temperature point of the reference cavity is measured by femtosecond light comb. The temperature control accuracy at this temperature point is 鹵5mK / day. The average linear frequency drift is less than 100 MHz / s after locking by PDH technique. The device has been successfully used in the side band cooling experiment of calcium ion.
