Abstract

The invention relates to a method for acquiring Raman laser, in particular to a method for acquiring continuous or pulse Raman laser, and solves the problems of low efficiency and very unstable of a light field of the Raman laser acquired by the existing method and large volume and complex structure of a device for generating the Raman laser. The method for acquiring the Raman laser comprises the following steps of: making first and second interference filtering devices; measuring the tuning ranges of resonant frequencies along with the temperature and the stabilities of the interference filtering devices; ensuring two sidebands of the laser to respectively pass through the first and second interference filtering devices and then be merged to obtain the continuous Raman laser; and regulating an arbitrary waveform function generator to obtain the pulse Raman laser. The Raman laser acquired by the method disclosed by the invention has high efficiency and stable light field; the device used in the method has simple structure; and the method can be widely suitable for the aspects of the preparation and the coherent operation and control of an atomic quantum state, the generation of a specific light source, the laser spectroscopy, quantum information and the like.

Description

technical field [0001] The invention relates to a method for obtaining Raman laser, in particular to a method for obtaining continuous or pulsed Raman laser. Background technique [0002] Raman (Raman) laser is a kind of laser whose frequency difference is equal to the hyperfine energy level difference of a specific atom and which is phase-locked. Spectroscopy and quantum information have a wide range of applications. With the development of cold atomic physics, quantum optics and quantum information, the increasing requirements for the coherent control of the internal state of atoms and the wide application of stimulated Raman adiabatic transport (Stimulated Raman Adiabatic Passage, STIRAP) technology, the preparation of Raman laser is becoming more and more important. Particularly important. Now people can use a variety of methods to generate Raman laser: (1) After a beam of laser light is passed through an acousto-optic modulator, it is modulated to generate Raman laser...
