Abstract
Single-frequency lasers are laser sources operating with only a single longitudinal mode and thus can emit quasi-monochromatic radiation with very narrow linewidth and ultra-low noise. Single-frequency operation of a laser has been realized with almost all of the current laser technologies. Such lasers, both in continuous-wave and pulsed operation, have been intensively investigated and developed due to their diverse applications. This article addresses the principle of single frequency operation of a laser, presents various techniques to develop and characterize single-frequency lasers, and discuss their applications.
