The Hamiltonian of the system interacting with a two-level atomic Bose-Einstein condensate (BEC) is given. The interaction between atoms in a system of squeezed coherent states and the atomic BEC is studied. The results show that both the fluctuations of the two orthogonal components of the light field change periodically with the cosine law and the compressibility depends on the initial compression factor and the compression direction angle of the light field, Effect of the fluctuation of the orthogonal component of the light field amplitude and period over time.
