| Abstract: | The conventional separation of states of the quantised radiation field into “classical” and “nonclassical” types is expressed
in a dual operator form and then refined. This is based on new features of the normal ordering rule for passage from classical
to quantum dynamical variables. The cases of single and two-mode radiation fields are discussed |
