The construction of a series of unitary decoupling transformations, wh
ich diagonalizes the multimode generalization of the Jaynes-Cummings m
odel and provides us with an extremely convenient basis to gain a deep
er understanding of the dressing processes present in the matter-radia
tion interaction, is presented.
