  We propose a theoretical method to enhance the coherent dipole coupling
between two atoms in an optical cavity via parametrically squeezing the cavity
mode. In the present scheme, conditions for coherent coupling are derived in
detail and diverse dynamics of the system can be obtained by regulating system
parameters. In the presence of environmental noise, an auxiliary squeezed field
is employed to suppress, and even completely eliminate the additional noise
induced by squeezing. In addition, we demonstrate that our scheme enables the
effective suppression of atomic spontaneous emission. The results in our
investigation could be used for diverse applications in quantum technologies.
