Laser generation in disordered systems based on arrays of ZnO nanocrystals of various morphologies obtained by the original hydrothermal method is studied. It was found that in a visually disordered system of nanocrystallites, a limited number of agglomerates playing the role of optical resonators may exist. Resonators can be considered as a closed structure generating radiation with certain repetitive parameters. The parameters and morphology of such resonators, as well as the nature of the laser radiation generated by them, are discussed. Keywords: zinc oxide, hydrothermal synthesis, nano crystals, ordered and disordered generation, resonators.
