Abstract

Laser heating of alkali metal vapor cells of atomic magnetometers is applied owing to its none magnetic field interference and little energy consumption, compared to heating by hot air and heating by AC electrical current. The development of laser heating technology, including the attachment of optical filters for better heat absorption, has expanded its usage from small chip-scale cells to relatively large cells, and from heating of single magnetometer to heating of an array of magnetometers. This paper offers a review of the evolution of laser heating in atomic magnetometers, introduces the different configurations of laser heating in experiments and points out the next possible target of the application of laser heating.
