摘要
The present application relates to a saturated absorption spectrum frequency stabilized laser optical path, and a saturated absorption spectrum frequency stabilized laser. The laser pumping is directed to the third reflective mirror after sequentially passing through the first reflective mirror, the second reflective mirror, the second polarizing beam splitter, and the gas chamber. After being reflected by the third reflective mirror, the laser pumping is output sequentially by the gas chamber, the fourth reflective mirror, and the first polarizing beam splitter. After being emitted from the first polarizing beam splitter, the detection light is sequentially directed to the third reflective mirror by means of the fourth reflective mirror and the gas chamber. After being reflected by the third reflective mirror, the detection light is directed to a detector by means of the gas chamber and the second polarizing beam splitter. An optical path of the laser pumping and that of the detection light in the gas chamber overlap with each other, and have the inverse direction. The length of the gas chamber can be reduced, and thus the volume and area occupied by the saturated absorption spectrum frequency stabilized laser optical path can be reduced for facilitating the use.
