IPG's RLR Series Raman Fiber Lasers are manufactured using IPG’s high power pump diode lasers, which operate over a wide temperature range without requiring thermoelectric coolers (TEC). RLR Series lasers are being deployed in demanding ultra-long-haul DWDM transmission systems to provide distributed Raman amplification and remote pumping of Erbium-doped Fiber Amplifiers (EDFAs). Raman Fiber Lasers offer a superior pump source over other techniques such as frequency multiplexed single-mode laser diode combiners by virtue of proven high reliability, cost, efficiency and watt class powers.
