Summary: | An optical amplifier (1000) for amplifying an optical signal (1002), the optical amplifier (1000) comprising: an optical fibre (1004), the optical fibre including a doped core (1006), an inner cladding (1008) extending substantially radially outwardly from the doped core (1006) and an outer cladding (1010) extending substantially radially outwardly from the inner cladding (1008); a signal coupler (1012) for receiving the optical signal (1002) and guiding the optical signal (1002) into the doped core (1006); a first pump light source (1014) for producing a first pump light having a first power, the first pump light source (1014) being optically coupled to the optical fibre (1004) at a first location therealong for guiding the first pump light into the inner cladding (1008) at the first location; and a second pump light source (1016) for producing a second pump light having a second power, the second power being larger than the first power, the second pump light source (1016) being optically coupled to the optical fibre (1004) at a second location therealong for guiding the second pump light into the inner cladding (1008) at the second location; wherein the first location is located between the signal coupler and the second location. |
