Paper Abstract

Measurements of the state of polarization of the output of a double-clad fiber laser with relatively large birefringence and dichroism as a function of pump power and externally induced anisotropic stress are reported. The laser field ellipticity and the laser gain dichroism show a sharp modulation across the optical spectrum; this spectral modulation has a characteristic length of 1.75 nm, determined by the fiber core birefringence. The laser output power is partially elliptically polarized with the degree of polarization having a value near zero below and well above laser threshold, and near one close to threshold.
