FIELD: laser engineering.
SUBSTANCE: multi-wave photoexcited thin-film organic laser comprises an optical pumping source, a laser-active element in form of a substrate, on which an additional layer is applied, which provides conditions for complete internal reflection for the generation wavelength and simultaneous adhesion to the substrate of an organic laser active medium consisting of an organic luminophore dissolved in the polymer. Laser-active element consists of several similar laser-active elements made with different luminophores folded into a stack and separated by air gaps equal to or greater than the maximum generation wavelength.
EFFECT: technical result consists in enabling simultaneous radiation at several wavelengths from one pumping source.
