Abstract :
In this work we study experimentally and theoretically spectral broadening of radiation in CW Yb-doped fibre laser. Averaged models dealing with an average optical power and neglecting the phase of optical field and time dynamics of the radiation are commonly used for analysis of CW fibre lasers. However, time evolution of the optical radiation might play an important role in performance of high power fibre laser even for so-called CW lasers. In this work we undertake experimental and numerical study of spectral broadening of radiation in fibre laser operating at 1084nm.
