Yb-doped Double-clad Active Fiber

Contact Us

Description

Ytterbium-doped dual-clad active optical fibers are suitable for use in fiber lasers and fiber amplifiers operating in the wavelength range of approximately 1000 - 1100 nanometers. There are options for single-mode and large-mode-area, with output powers ranging from milliwatts to kilowatts. The cladding diameters are 130 microns or 400 microns, conforming to the industry standards for active optical fibers.

Features

Cladding pump design;
Single mode or LMA working;
High pump absorption and low photodarkening;
High slope efficiency;

Applications

Pulse amplifier with high average power;
Medium and high power pulses, and continuous wave laser;
Material handling;
Laser radar;
