摘 要：正Nonclassical light beams generated by degenerate and non-degenerate optical parametric oscillators （ OPO） have played a significant role in studies of squeezing, entanglement and other nonclassical properties of light. Fluctuation properties of these nonclassical light beams have been studied by using various coherent state representations of the field density matrix. Here we discuss the use of positive-P representation of the density matrix
