Reported for the first time is picosecond-range pulse generation in an all-fibre Raman laser based on P2O5-doped silica fibre. Employment of phosphor-silicate fibre made possible single-cascade spectral transformation of pumping pulses at 1084 nm into 270-ps long Raman laser pulses at 1270 nm. The highest observed fraction of the Stokes component radiation at 1270 nm in the total output of the Raman laser amounted to 30%. The identified optimal duration of the input pulses at which the amount of Stokes component radiation in a similar to 16-m long phosphorus-based Raman fibre converter reaches its maximum was 140-180 ps.
