Research Progress on the Alkali Metal Atomic Vapor Cell

The alkali metal atomic vapor cell is the core component of quantum devices such as atomic gyroscope, atomic magnetometer and atomic clock. High performance micro-miniature atomic vapor cell is one of the important factors restricting the developments of the above quantum devices. In this paper, the research progress of the atomic vapor cell from the aspects of theoretical research, manufacturing technology and bulb material is summarized. The key technologies are analyzed and discussed, such as optical precision machining of glass micro cell, precise filling technology of alkali metal and gas mixture, high-temperature antirelaxation surface coating technology, cure technology with bake process. In view of micro-miniature, high-precision, integrated design for quantum devices, the development trend of alkali metal atomic vapor cell is also outlined.
