Abstract：
 The present invention relates to a method for raising output power of fibre-optic laser and quality of its optical spectrum and beam, belonging to the field of laser and optoelectronics. Said invention is characterized by that it utilizes forward phase conjugation and backward phase conjugation to suppress the stimulated Raman scattering effect and compensate the effects of harmful nonlinear optics and thermal aberration, etc. so as to raise the output power of fibre-optic laser and quality of its optical spectrum and beam.
