摘要： We explore the theoretical possibility of extending the usual squeezed state to those produced by nonlinear single-mode squeezing operators. We derive the wave functions of exp[-(ig/2)(√1-X2P+P√1-X2)]|> in the coordinate representation. A new operator's disentangling formula is derived as a by-product.
