Experimental investigation of various fibre lasers containing rare-earth ions shows that the polarisation effects, with a Fabry-Perot cavity, can be characterised by three basic factors: (i) The fluorescence caused by spontaneous emission is depolarized independently of the polarisation of the pump light; (ii) Two orthogonal, phase-independent, polarisation eigenmodes exist in the "singlemode" fibre laser cavity; (iii) The polarisation state of the output from the fibre laser depends on the orientation of the pump light polarisation, the pump power level and the dopant characteristics. The evidence of polarisation effects in a Nd3+-doped fibre laser can be clearly seen from Figures 1,2 and Reference 1
