Raman Fibre Lasers

Superior pump sources   

CW Raman Fibre Lasers   

The RLR series of Raman fibre lasers incorporate IPG’s high power pump diodes to offer a superior pump source over other techniques such as frequency multiplexed single-mode laser diode combiners. The lasers operate over a wide temperature range without requiring thermoelectric coolers (TEC), delivering proven high reliability, efficiency and powers up to 100 W.


  • Distributed Raman amplification
  • Remote fibre amplifier pumping
  • Ultra-broadband Amplifiers


  • Wavelength range: 1200 to 1500 nm
  • Up to 100 W Output Optical Power
  • Single or Dual Wavelength Option
  • Wide Operating Temperature Range

The RLR Series Raman fibre lasers consist of two components - a Ytterbium fibre laser and a Raman wavelength shifter. The Ytterbium laser is an IPG YLP single-mode fibre laser operating at wavelengths between 1050 and 1120 nm. The Raman shifter employs a cascaded Raman resonator utilising Bragg fiber gratings to efficiently convert the input pump laser wavelength to the chosen output wavelength. For example, 1064 nm converts to 1480 nm. The output is single-mode and randomly polarised.
