Abstract
We investigate the limits of validity of models commonly used to describe all-fiber Raman lasers. To this end, we record the characteristics of an all-fiber Raman laser in which pump and Stokes waves remain linearly polarized. We show that they significantly deviate from the characteristics predicted by the usual model. The observed discrepancy arises from spectral broadening effects leading to a decrease of the mean reflectivity of the fiber Bragg grating mirrors with the incident pump power. Usual single-mode and multi-mode models are shown to be irrelevant to describe these effects. We also show that coupling among longitudinal modes must be taken into account for further modeling of spectral broadening.
