A modification of the Z-scan technique for measuring nonlinear refractive index n₂ in the terahertz spectral region is proposed. Measurements are made at a broadband terahertz radiation intensity of 0.8 × 10⁹ W cm⁻². Coefficient n₂ = 2.5 × 10⁻¹¹ cm² W⁻¹ is estimated for semiconductor crystalline ZnSe.
