Abstract

A method for stabilize and integrating frequency of atomic dichroism laser the fixed magnetic field required for the frequency stabilization technique based on the atomic dichroism laser is provided by the external magnetic field of the optical isolator. The permanent magnet or energized coil and the power supply and control circuits which provide the required magnetic field environment in the original system are omitted, the external magnetic field of the optical isolator is effectively utilized, and the device of laser frequency stabilization based on DAVLL is simplified. In this method, theatomic gas chamber is placed on one side of the optical isolator, and the magnetic field required for DAVLL is supplied by the optical isolator, which splits and shifts the atomic energy level in theatomic gas chamber due to Zeeman effect, so that the laser frequency stabilization based on DAVLL is realized. The invention reduces the device number of the laser frequency stabilization device based on DAVLL, reduces the volume of the device, and improves the integration level of the device.

Description

technical field

[0001] The invention belongs to the technical field of laser frequency stabilization, and in particular relates to an integrated method for atomic dichroic laser frequency stabilization. Background technique

[0002] In recent years, with the rapid development of semiconductor laser frequency stabilization technology, semiconductor lasers with narrow linewidth and high stability have been increasingly used in optoelectronics fields such as atomic spectroscopy, quantum metrology, optical fiber communication, atomic magnetometer, and laser atom cooling. Wide range of applications. Among them, the frequency stabilization method based on DAVLL (Dichroic Atomic Vapor Laser Lock, dichroic atomic vapor laser frequency locking) has a simple structure, no external modulation signal (internal modulation), wide frequency stabilization range, and low requirements on the magnetic field. The magnitude of the magnetic field strength will only affect the slope at the zero p...
