Nufern Introduces Optical Amplifier Modules

Built using Nufern single-mode and large-mode area double-clad fiber


EAST GRANBY, CONN. - (May 23, 2005) — Nufern, the largest independent manufacturer of fiber laser and amplifier modules and specialty optical fibers, announced the release of a new series of fiber amplifiers that incorporate Nufern’s industry leading single-mode and large-mode area (LMA) double-clad fibers. For years, Nufern has been building custom amplifier modules into various applications at different power levels, pulse widths, peak powers and line widths.

The new line of standard optical amplifier modules is designed to address a broad range of market requirements:

• TEM00 Gaussian output (M2 1.5)
• Greater than 13 dB gain
• High polarization extinction ratio > 19 dB
• High peak power, pulsed (fs, ps, ns) amplification
• High and low average power (CW) amplification
• Narrow line width (kHz) amplification

“The highly engineered design of these standard amplifiers draws on our years of experience building custom systems”, says Dave Machewirth, Director of Engineering. “The fiber amplifiers are optimized to achieve maximum efficiency and to avoid detrimental effects such as non-linear absorption, splice losses and self Q-switching”.

The basic amplifier modules include an active gain fiber and a multi-input pump combiner that can accommodate a number different pump diode configurations and wavelengths. Nufern amplifiers are also available with a broad range of complimentary options including pre-packaged, pre-spliced diodes, end cap assemblies, pump dumps, connectors, OEM packaging and optimized configurations for non-standard wavelengths.

Nufern’s amplifier modules offer efficient, optical performance and reliability with a range of applications including sensing, range finding, LIDAR, marking, micromachining, precision material processing, helium pumping, and spectroscopy.
