Abstract
The practical aspect of the moment problem for a density matrix for single-mode radiation is solved; namely, two simple explicit expressions for the density matrix in terms of its moments are presented. A biorthogonal set of operators is established, so that two bases are available for expressing an arbitrary operator.
