There is provided a system for remote pumping of a Raman fiber amplifier comprising a pump laser located remotely from the Raman fiber amplifier and a laserhead and one or more optical fibers to optically couple the high power pump light from the remote pump laser to the Raman fiber amplifier where a seed laser light is amplified wherein the pump laser for producing a high power laser light of a predetermined pump wavelength comprises a first fiber laser emitting light at the predetermined pump wavelength and one (second) or two (third) laser emitting light at a wavelength lower than the predetermined pump wavelength and multiplexed with light from the first laser into an optical fiber providing Raman gain at the predetermined pump wavelength to convert the second (and optionally also the third) laser light to light at the predetermined pump wavelength.
