This Erbium/Ytterbium co-doped double-clad fiber features a large mode area and high doping concentration, which are key parameters for the development of eye-safe high-power fiber lasers. The DCF-EY-16/128-18’s high slope efficiency makes this fiber ideal for the design of high-power/peak power eye-safe pulsed fiber lasers and amplifiers for LiDAR applications.

Features & Benefits
