Fiber Laser Basics

Time: Sep 23,2020 Author: Sintec Optronics View: 2074

A fiber laser (or fibre lase) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing. A fiber laser with MOPA configuration is shown as follows:
