Magnetometer Based on Single-Pass Generation in Alkali Metal Atomic Vapours
Abstract
A description of a simple magnetometer is given, in which single-pass generation is realized on vapours of rubidium/cesium atoms located in an optical cell of several centimeters long, when resonant laser radiation with a wavelength of 852 nm (in the case of Cs) or 780 nm (in the case of Rb) passes. It is demonstrated that at the degenerate two-level cyclic transition Fe>Fg, an inverse population is realized between the upper and lower Zeeman sublevels. The sensitivity (change) of the output power of the generated radiation with a change in the external magnetic field by ~70 nT is achieved. It is shown that the system can function as a metal detector, and an advantage over commercial metal detectors is noted.
