OXFORD, Mass. -- IPG Photonics, the world leader in high performance fiber amplifiers and fiber lasers, announced today the introduction of its discrete Raman amplifiers providing high gain and low noise amplification across the entire standard optical fiber low loss region from 1260 nm to 1700 nm. RAR Series amplifiers can be used in next generation long haul and product development applications and offer many advantages over EDFAs and direct-diode pumped Raman amplifiers.The new RAR Series is IPG’s multiple-wavelength pumped Raman amplifier providing 50 nm to 100 nm of optical bandwidth for dense wavelength division multiplex (DWDM) amplification. Single-wavelength pumping options for narrower bandwidth requirements are available.Dr. Denis Gapontsev, IPG’s Vice President of R&D, said “these discrete Raman amplifiers offer a simple and cost-effective method of providing optical gain at regions not presently covered by doped fiber amplifiers or where higher output powers are required than can currently be achieved.” He added “we can quickly tailor and re-design our amplifiers to provide the operating region, gain profile and bandwidth required.”IPG Photonics Corp.
