Do I need to set chi1 if I already set the base material?

      Dear all,

               I wanna investigate the nonlinear properties of GaN.I am wondering if it is necessary to set the chi1 value and I find it hard to find chi1 in papers.

      You do not need to specify it as the base material is sufficient.

        Could you please tell me what it would be if I set both the chi1 and the base material?

      It follows the non-linear optics that Chi1 under proper E intensity creates a purturbation to the base material.
