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.

Applications

Distributed Raman amplification
Remote fibre amplifier pumping
Ultra-broadband Amplifiers

Features

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

Technology
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.
