Abstract: The features of the two-photon absorption spectra during the photoionization of $D^-$ centers in a quasi-two-dimensional structure with disk-shaped quantum dots are studied using the zero-radius potential method. The case of quasi-stationary $D^-$ states in a quantum disk is considered. It is shown that the dichroism of two-photon impurity absorption is associated with a change in the selection rules for the magnetic quantum number in the radial direction, and taking into account the dispersion of the characteristic dimensions of the quantum disk leads to blurring of lines in the spectral dependence of the two-photon absorption coefficient.
