ErYb 7/125 Polarization-Maintaining Optical Fiber
The single-mode core of this polarization-maintaining fiber is co-doped with both erbium and ytterbium. It is then surrounded by a silica cladding and covered with a low-index protective coating. The resulting double-clad fiber is used for single-mode fiber lasers and amplifiers operating in the 1540 to 1565 nm range.
The fiber enables fiber lasers and amplifiers with good beam profile characteristics, high wall plug efficiencies, compact footprints, superior reliability, and maintenance-free operation. It also accomodates high energies during pulsed operation and at high repetition rates.
