Abstract: The phenomena of squeezing and correlation of quantum fluctuations in the correlated coherent states of two oscillatory modes with a parametric coupling of coordinates are investigated. Under the conditions of strong mode coupling both the excitation and strong correlation of quantum fluctuations are discovered. The matrix of dispersions and covariances of dynamical variables is found explicitly with the use of the method of linear quantum integrals of motion.
