A type of special two-mode squeezed coherent state is constructed which is a characteristic of squeezing and displacing related. The new states rake simpler and neater form than the usual two-mode squeezed coherent states, and also possess a completeness relation. It is expected that experimentalists woking on quantum optics should fabricate such a type of squeezed coherent optical field.
