| description | The invention provides a double-field light source frequency locking method and system based on a gas chamber frequency reference, and relates to the technical field of quantum key distribution, double-field light sources lock the light sources on the gas chamber frequency reference through respective gas chamber frequency reference locking systems, one beam of laser signals is coupled to a molecular absorption cell and detected by a second photoelectric detector, and the other beam of laser signals is coupled to a second photoelectric detector. The other beam of laser signal is detected by a first photoelectric detector, frequency detuning information is obtained, an error signal is generated, and finally the laser is locked on a frequency reference of the gas chamber; a first light source of the double-field light source emits continuous laser locked on the gas chamber frequency reference, and a second light source locked on the gas chamber frequency reference emits continuous laser; the detection end recei |
