A wavelength locker, wavelength locking method and device

The embodiment of the invention provides a wavelength locking device, a wavelength locking method and a device, so as to solve the problem that the correct frequency shift can not be detected at the time of large wavelength drift, and the high accuracy in the full band range can not be achieved. The wavelength locking detection processing circuit of the reactor, according to the optical signal of the first F P etalon transmission and reflection, and the second F P etalon for reflection and transmission of optical signals, pin current adjustment of the laser, the frequency shift of the laser in the error range; the minimum detection precision of the linear region of the frequency range of a periodic transmission function of the first F P etalon in less than the demand; two times the maximum frequency shift cycle length transmission function of the second F P etalon is not less than the laser light signal of the frequency; the preset wavelength at the first F P etalon transmission function and the transfer function of second F P etalon linear region.
