The organic semiconductors BODIPY derivative was studied for lasing application. The nematic liquid crystal doped with BODIPY derivative was researched as gain medium for distributed feedback laser. Reflection spectrum for nematic liquid crystal and emission spectra of nematic liquid crystals doped with BODIPY derivative at the laser pumping with wavelength of 532 and 515 nm were determined. Obtained spectra correspond to the regime which is close to the threshold.
