Overview of Faraday Lasers
摘要
A FaradayFaraday laser is a type of laser that uses a FaradayFaraday Anomalous Dispersion Optical Filter (abbreviated as FADOF), which is a new type of diode laser that uses a selective frequency component. In principle, the output wavelength of the FaradayFaraday laser directly corresponds to the atomic transition spectrum line, and the laser frequency is always restricted within the transmission bandwidth of the atomic filter. In addition, the FaradayFaraday laser has the ability to resist disturbances in the driving current and operating temperature of the laser diode, and has the advantages of automatic output frequency corresponding to atomic transitions, long-term continuous operation, and immediate use. This chapter provides a detailed introduction to the basic working mechanism, structure, and performance advantages of the FaradayFaraday laser, as well as its application in fields such as quantum precision measurement.
