Abstract: Materials with a near-zero refractive index open up new possibilities for enhancing nonlinear optical interactions. This lowers the threshold for nonlinear generation, reduces the size of existing nonlinear devices, and opens up prospects for new applications. In this work, the enhancement of stimulated Raman scattering (SRS) in materials with near-zero permittivity is studied. It is shown that the frequency shift of the Stokes wave gain is observed in these media, which leads to the shift of the SRS lines. In addition, a condition for the permittivity of the medium is obtained under which the SRS gain reaches its maximum value.
