Nufern's industry leading double-clad fibers are now available in a standard series of fiber amplifier modules. These robustly engineered amplifiers combine a carefully designed length of double-clad gain fiber with a complementary tapered diode pump combiner. The signal input seeds the amplifier through a single-mode feedthrough which maintains the spectral (line width, wavelength, polarization, etc.) and temporal integrity of the source through an ultra low loss splice onto the gain fiber. Efficient amplification occurs in the cladding pumped single-mode or large-mode area gain fiber.

Nufern amplifiers are available with a broad range of complementary options including pre-packaged, pre-spliced diodes, end cap assemblies, pump dumps, connectors, OEM packaging and optimized configurations for non-standard wavelengths. Contact us for details.
