In this article we present the results of studies carried out on the selected polymeric systems doped with luminescent dyes. Our studies focused on polymers like DNA-CTMA and PVK which were doped with common laser dyes Rh6G and DCM. We show that simple incorporation of highly luminescent dye into polymeric matrix can form ;efficient solid laser materials. Moreover, naturally occurring inhomogeneities of polymeric layers prepared by a drop casting process can scatter out pumping light in such a way that a feedback is introduced to the system and coherent and incoherent random lasing can be observed.
