Abstract
Using the newly developed technique of integration within an ordered produc t of operators, we prove that single-mode (or two-mode) squeezed states spa n a complete space in squeezing parametric space. The proof is concise and direct, and no further knowledge of SU(1,1) general coherent state theory i s needed in our discussion.
