We have confirmed the suggestion of Gibson and Österberg [Opt. Lett.30, 1827 (2005)] that the lasing action observed in Rhodamine 6G-doped microstructured polymer fibers [Argyros, Opt. Lett.29, 1882 (2004)] is due to stimulated Raman scattering. The Raman scattering occurs in the poly(methyl methacrylate) host material, and upon further investigation emission up to the third Stokes order was observed. Lasing of the dye in a microstructured polymer fiber was achieved with a modification of the fiber properties.
