Cladding Pumped Fiber Design

Erbium-Ytterbium 130 µm Cladding Pumped Fibers

(2)

The single-mode core of this fiber is co-doped with 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 1565nm range.

These fibers can be used with OFS compatible beam combiners to design gain modules for CATV amplifiers, also known as Erbium Ytterbium Doped Fiber Amplifiers (YEDFAs). A few benefits of OFS erbium-ytterbium fibers are: good beam profile characteristics, high efficiency, compact amplifier footprint, high reliability, and maintenance-free operation.

Cladding Pumped Fiber Design

Ytterbium 130 µm Cladding Pumped Fibers


The single-mode core of this fiber is doped with 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 1040 to 1200 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 accommodates high energies during pulsed operation and at high repetition rates.
Polarization-Maintaining Erbium-Ytterbium 125 µm

Polarization-Maintaining Erbium-Ytterbium 125 µm Cladding Pumped Fibers


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 accommodates high energies during pulsed operation and at high repetition rates.

Configuration of FemtoComp

FemtoComp Dispersion Compensation Modules


A FemtoComp Module is a fully fiber-based device for dispersion management in femtosecond lasers and amplifiers working at a wavelength around 1 µm. FemtoComp has an anomalous dispersion in the 1 µm wavelength region and can therefore compensate the normal dispersion in standard fibers. FemtoComp is based on a solid silica-based fiber, which supports guidance of a higher order mode (HOM) with anomalous dispersion. Long period fiber grating (LPG) based mode converters in both ends of the fiber convert between the fundamental mode (LP01) and the higher order mode. The mode converters are pigtailed with standard single mode fiber (ClearLite® 980 14) for 1 µm applications.
