Atomic gas chamber with high transmissivity, manufacturing method of atomic gas chamber and atomic magnetometer

The invention discloses an atomic gas chamber with high transmissivity, a manufacturing method of an atomic gas chamber and an atomic magnetometer. The atomic gas chamber comprises: a glass gas chamber, wherein the two opposite sides of the glass gas chamber are provided with a first through hole and a second through hole; a first cavity mirror structure which is arranged on one side, far away from the second through hole, of the first through hole; a second cavity mirror structure which is arranged on one side, far away from the first through hole, of the second through hole; a first multi-reflection cavity which is arranged on the surface of one side, deviating from the first through hole, of the first cavity mirror structure; and a second multi-reflection cavity which is arranged on the surface of the side, away from the second through hole, of the second cavity mirror structure. According to the technical scheme provided by the invention, the multiple reflection cavities are arranged outside the glass gas
