Abstract	We demonstrate a high-gain, cascaded fibre Raman amplifier, operating at 1.3 pm. Raman generation and amplification are achieved in a ring resonator constructed solely from fused fibre WDM couplers with low-loss GeOz-doped single mode fibre used as the active medium. The amplifier is pumped by a Nd:YAG laser at 1.064 p.m. In our resonant cascaded geometry, this generates the third Stokes line at 1.24 pm, which acts as a pump for Raman amplification of signals around 1.3 km. A gain of 28 dB is demonstrated with output signal powers of up to 20 dBm for 3.4 W of pump power. Our experiments also indicate the important role of filters to suppress feedback in the resonator, permitting high Raman gain and good signal quality. 0 1997 Elsevier Science B.V.
