A thin‐film, organic solid‐state laser operating in the ultraviolet wavelength region is fabricated using a novel spiro‐linked material as an active organic layer in an optically pumped distributed feedback (DFB) structure. The laser could be tuned between 377.7 nm and 395 nm by varying the grating period of the substrate and was utilized as the excitation source for solutions containing biomarker fluorescent dyes (see Figure and inside cover).
