Bloch-Messiah decomposition and Magnus expansion for parametric down-conversion with monochromatic pump: role of the gain
We consider the effect of different orders of Magnus expansion for the field transformation in type-I parametric down-conversion with a monochromatic pump. The exact solution, existing in this case, allows us to analyze the convergence of the Magnus expansion for the spectrum of squeezing and the an...
