Plug-and-play access type three-light microwave atom sensor

The utility model discloses a plug-and-play access type three-light microwave atom sensor, which comprises laser optical fiber input interfaces including a first laser optical fiber input interface, a second laser optical fiber input interface and a third laser optical fiber input interface, the device further comprises a 45-degree silver-plated reflector, a depolarization splitting prism, a first polarization splitting prism, a long-wave-pass dichroic mirror, an Rb air chamber, a second polarization splitting prism, a short-wave-pass dichroic mirror and a vertical silver-plated reflector. According to the utility model, three laser beams required by the operation of the sensor are thoroughly separated from a sensing physical action part, so that the device of the sensor part is realized, and large-scale production and application are facilitated; the shockproof function is achieved; the complexity of optical fiber access is simplified; and the use complexity of the whole sensor is reduced. 本实用新型公开了一种即插即用接入式三
