  Quantized descriptions of nonlinear-optical processes can be relevant from
the perspective of developing novel nonclassical sources of light. As a special
case, it is useful to characterize light emitted by classically driven systems,
since the excitations in many practical cases are laser beams. As a material
model, we choose a two-level system. In an earlier work, we investigated photon
statistics and intermodal cross-correlations Phys. Rev. A 104(3):033703,
(2021), and noted that squeezing is primarily present in specific sets of
parameters, corresponding to the degeneracy of hyper-Raman lines. Here we focus
on this specific set of parameters, presenting details of the squeezing.
