“…This type of structure still has limitations such as large system size, high level of difficulty in the installation and adjustment of the optical path, susceptibility to external light noise, and higher loss than the Littrow-ECDL. Currently, researchers at Central China Normal University [66], Universidad Carlos III de Madrid in Spain [67], Aston University in England [68], and Sacher Lasertechnik in Germany [69], among other institutions [70][71][72] have conducted Littman-ECDL research.…”

“…In 2019, Hoppe et al [69] from Sacher Lasertechnik in Germany proposed a new type of Littman external-cavity structure based on a MEMS system to further improve stability, repeatability, tuning range, and speed. In this new structure, the laser beam is first irradiated on the rotatable MEMS mirror and then reflected on the reflective grating.…”

The external-cavity diode laser is advantageous in terms of low noise, high side-mode suppression ratio, high temperature stability, simple structure, and low cost, which has been the preferred scheme to realize wide-tuning and narrow-linewidth characteristics. Thus, it has been widely used in optical communication, lidar, environmental monitoring, spectral analysis, optical coherence tomography, and other frontier fields. Herein, we introduce the technical scheme and review the development status of wide-tuning and narrow-linewidth external-cavity diode lasers in detail. Primarily, the structure, working principles, and performance characteristics of external-cavity diode lasers are deeply analyzed according to different structures. The structural characteristics, key technologies, optical performance and application fields of state-of-theart studies in recent years are discussed. Finally, the challenges and potential development prospects of wide-tuning and narrow-linewidth external-cavity diode lasers are analyzed and discussed.
