Micro atom steam bubble making method

Abstract

The invention relates to atom steam bubble, in particular to a micro atom steam bubble making method. The method solves the problem that the existing micro atom steam bubble making method is too high in production cost owning to high requirement on technology and device and includes the following steps: a micro glass cavity with two parallel end faces and a minor diameter through hole opened on the sidewall is selected; the micro glass cavity is placed in an enclosed glass ware with a ZnSe glass window on the sidewall and just below a glass rod in the enclosed glass ware, wherein the through hole is over against the glass rod, and the enclosed glass ware is vacuumized and filled with inert gases and alkaline metal steam; the enclosed glass ware is heated, the end part of the glass rod is radiated by high power laser through the ZnSe glass window by a laser, so that the glass rod is dissolved to small liquid beads and drops into the through hole to seal the through hole; the micro glass cavity is taken out; the parallel end faces of the micro glass cavity are polished and plated with an anti-reflection film. The technology is simple and reasonable, the applying device is simple, and the production cost is low, thus being applicable to making micro atom steam bubble and having important significance.

Description

technical field [0001] The invention relates to atomic steam bubbles, in particular to a method for manufacturing miniature atomic steam bubbles based on non-silicon technology. Background technique [0002] Atomic vapor bubbles are the core components of miniature atomic optical devices such as miniature magnetometers, miniature atomic clocks, and miniature nuclear magnetic resonance gyroscopes. At present, the more commonly used atomic vapor bubble production methods are as follows: 1. Glass blowing method, using a glass tube with a vent tube on the side wall, and two optical glass sheets are bonded to the two end faces of the glass tube by melting or chemical bonding. The connection is fixed, the air in the glass tube is evacuated through the vent tube on the side wall of the glass tube, and then the required inert gas and alkaline metal vapor are filled into the glass tube through the vent tube on the side wall of the glass tube, and finally the vent tube is melted and s...
