摘要： By virtue of the Weyl ordering method, we find a new formalism of optical field operator expansion in number state representation. Miscillaneous optical fields' (coherent state, squeezed field, Wigner operator, etc.) new expansions are therfore exhibited. Some new generating function of special polynomials are derived herewith.
