We demonstrate an optical method to engineer optical Schrodinger cat states (SCSs) of large amplitude in the range from 2 to 3 with high fidelity close to 0.99. The approach uses the {\alpha}-representation of the SCSs in infinite Hilbert with base displaced number states characterized by the displacement amplitude {\alpha}. An arbitrary {\alpha}-representation of SCSs enables to manipulate the amplitudes in wider range of parameters that which greatly expands the possibilities for generation…
