The photoluminescence of a donor-doped laser nanostructure n GaAs/AlGaAs with quantum wells in the terahertz and near infrared ranges is investigated. Radiative transitions of electrons through the excited and ground levels of the donor were found in the spectral dependences of terahertz and near infrared photoluminescence. The stimulated radiation with the participation of impurity centers was investigated, its effect on the intensity of terahertz radiation was found. Transformation of terahertz radiation spectra was recorded depending on which the donor state through stimulated radiation in the near infrared range prevails.
