  We introduce a new method for constructing squeezed states for the 2D
isotropic harmonic oscillator. Based on the construction of coherent states in
[1], we define a new set of ladder operators for the 2D system as a linear
combination of the x and y ladder operators and construct the SU(2) coherent
states. The new ladder operators are used for generalizing the squeezing
operator to 2D and the SU(2) coherent states play the role of the Fock states
in the expansion of the 2D squeezed states. We discuss some properties of the
2D squeezed states.
