Apparatus and method for adjusting the transmission properties of a light beam in an alkali atom cell

Abstract

The application relates to a device and a method for adjusting the transmission performance of a light beam in an alkali metal atom cell. The device comprises a detection system and a cell assembly. The cell assembly comprises a fiber input light source, an alkali metal atom cell, a mounting frame and an adjusting mechanism. The alkali metal atom cell is configured to be filled with alkali metal atoms and buffer gas. The alkali metal atom cell is connected to the adjusting mechanism through the mounting frame. The detection system comprises a detection piece for detecting the light spot morphology of the light beam emitted by the fiber input light source after passing through the alkali metal atom cell. The adjusting mechanism is configured to move the mounting frame to adjust the position of the alkali metal atom cell. The light spot morphology of the light beam after passing through the alkali metal atom cell can be detected in real time by the detection piece. The placement position of the alkali metal atom cell can be adjusted by the adjusting mechanism to adjust the light spot morphology of the light beam after passing through the alkali metal atom cell, thereby improving the transmission performance of the light beam in the alkali metal atom cell.
