Modification of the initial state a the mapping of quantum state in parametric amplifier.

Transformaiton of the rectangular mesh at the mapping of the phase space. At the input of the amplifier, there is the coherent sate with parameters $\alpha=\alpha_1+{\rm i}\alpha_2$. During the evolution with Hamiltonian $\frac{-\rm i}{2}\Big( a^2 b^\dagger - (a^\dagger)^2 b \Big)$. The state of pump mode with filed $b$ is also coherent with parameter $\beta\!=\!2$. Furation of evolution: $t\!=\!0$, $t\!=\!0.3$, $t\!=\!0.5$ (at the bottom).
