Abstract | An optical amplifier for amplifying an optical signal (1002), the optical amplifier comprising: an optical fibre, the optical fibre including a doped core, an inner cladding extending substantially radially outwardly from the doped core and an outer cladding extending substantially radially outwardly from the inner cladding; a signal coupler for receiving the optical signal and guiding the optical signal into the doped core; a first pump light source for producing a first pump light having a first power, the first pump light source being optically coupled to the optical fibre at a first location therealong for guiding the first pump light into the inner cladding at the first location; and a second pump light source for producing a second pump light having a second power, the second power being larger than the first power, the second pump light source being optically coupled to the optical fibre at a second location therealong for guiding the second pump light into the inner cladding at the second location; wherein the first location is located between the signal coupler and the second location. |
