Manufacturing method for mini quartz glass atomic gas chamber

Abstract

The invention discloses a manufacturing method for a mini quartz glass atomic gas chamber. The method comprises the following steps of encapsulating alkali-metal atoms into a glass micro-cavity and filling inert gas; manufacturing a lower-layer encapsulation block, a middle-layer encapsulation block and an upper-layer encapsulation block; assembling the lower-layer encapsulation block, the middle-layer encapsulation block, the upper-layer encapsulation block and the glass micro-cavity and sealing to form a closed cavity; heating a plurality of closed cavities at the temperature higher than the softening point of the glass micro-cavity and stopping heating until the glass micro-cavity structure is destroyed; and cutting the closed cavities after stopping heating based on the middle-layer encapsulation block in order to form the mini quartz glass atomic gas chamber. Through setting of the glass micro-cavity, the degree of purity of the atomic gas chamber is guaranteed, the problems of large difficulty of the conventional mini atomic gas chamber manufacturing process and poor degree of purity of the cavity are solved; through simultaneous heating of the closed cavities, the mass production of the atomic gas chamber is realized, and the defects of high requirements and difficulty in mass production of the conventional mini atomic gas chamber manufacturing equipment are made up.
