Symmetries of second-order nonlinear susceptibility tensor for GaSe by investigating THz generation

In this paper, we demonstrate that THz generation can be a sensitive technique for investigating violations of Kleinman's symmetry condition and spatial symmetry of second-order nonlinear susceptibility tensor for GaSe.
