Abstract :
Continuous wave single-pass Raman generation has been observed in optical fibres. Experiments showed that the first and the second Stokes have been observed with 0.6 W and 4.8 W of 1.064 ¿m pump power input, respectively, in a 35 km single-span VAD (vapour phase axial deposition) fibre with the loss of 1.13 dB/km at 1.064 ¿m. The threshold for the CW first Stokes was 1.25 W and complete conversion of the pump to the first Stokes was obtained with the pump power of 4 W.
