The report on a study of laser emission from a conceptually new organic material based on transparent wood (TW) with embedded dye Rhodamine 6G molecules is presented in this paper. The lasing performance is compared to a reference organic material containing dye in a poly‐methyl‐methacrylate matrix. From experimental results, one can conclude that the optical feedback in dye‐TW material is realized within cellulose fibers, which play the role of tiny optical resonators. Therefore, the output emission is a collective contribution of individual resonators. Due to this fact, as well as low Q‐factor of the resonators/fibers and their length variation, the spectral line of laser emission is broadened up to several nanometers.
