Method for laser output with separated field technology and separated field laser

Abstract

The utility model provides a method that realizes laser output by using the separation field technology, belonging to the laser technical field. The method utilizes the separation field technology to divide the laser resonator into two or more folded parts; the atoms and the laser resonator are coupled at a plurality of times; the interaction time of the atomic beam and the resonator is increased; the influence of flight time broadening to laser line width is reduced; therefore, the line width of the output laser is obviously thinner than common laser. The utility model also provides a separation field laser; the laser gain medium of the laser and the field mode of the laser cavity have a plurality of coherent interactions separated on the time domain; the separation field laser has the advantages of good frequency stability and high frequency accuracy.

Description

technical field [0001] The invention belongs to the field of laser technology, and specifically relates to a method and equipment for realizing laser output by using separation field technology. The generated laser can be used as a coherent laser light source with high accuracy and stability, and can also be used as a high-performance optical frequency standard. Background technique [0002] N.F. Ramsey proposed the separation field technology in 1949 and won the 1989 Nobel Prize in Physics for his successful application of the frequency standard (atomic clock). Ramsey's separated-field technique has been the basis for all high-performance reference atomic clocks and atomic interferometers to date. But so far, all separation field techniques are only used to measure the absorption spectrum of the electromagnetic field by physical particles, and have never been used for the generation or measurement of the stimulated emission electromagnetic field of physical particles. In o...
