High Power Fiber Lasers: A Review
TLDR
In this article, the fundamental properties and latest developments in high-power fiber lasers are summarized and reviewed, focusing primarily on the most common fiber laser configurations and the associated cladding pumping issues.Abstract:
In this paper, we summarize the fundamental properties and review the latest developments in high power fiber lasers. The review is focused primarily on the most common fiber laser configurations and the associated cladding pumping issues. Special attention is placed on pump combination techniques and the parameters that affect the brightness enhancement observed in single-mode and multimode high power fiber lasers. The review includes the major limitations imposed by fiber nonlinearities and other parasitic effects, such as optical damage, transverse modal instabilities and photodarkening. Finally, the paper summarizes the power evolution in continuous-wave and pulsed ytterbium-doped fiber lasers and their impact on industrial applications.read more
