CW RAMAN FIBER LASER for distributed raman amplification

"A Raman fiber laser can be used in many different applications as distributed Raman amplification, remote EDFA pumping or Telcordia fiber optic components testing. Lumibird patented architecture is offering high optical efficiency and high beam quality. The principle of operation involves utilization of a high-power and a compact ytterbium fiber laser source to pump a cascaded Raman resonator. Then the high conversion efficiency is achieved from the fundamental pump laser to final Raman Stokes. CRFL provide up to 20W output power at 1455nm or 1480nm. And the output diffraction limited beam is unpolarized. Also, a high stability is performed thanks to the high-level quality conception. Raman lasers are reliable and maintenance free, they can work continuously over an extended period. Lumibird choose the best components and submits lasers to a complete tests program to ensure that they are conformed to the datasheet."
