In this work we study optically pumped polymer-based lasers doped by various organic dyes in two different configurations, namely plane cavities of various shapes and vertical external cavities ("VECSOL"). The intrinsic fluorescence anisotropy of specific dye molecule together with the polarization state of the pump beam defines the basic emission properties of such dye-doped polymer system. The nonlinear enhancement of amplified spontaneous emission (ASE) and lasing results in the forcing of the emission properties and particularly of their polarization features. However, we demonstrate experimentally that it is possible to release this constraint and to obtain laser emission with a polarization state different from that of the pump.
