Wavelength variation of the second-order nonlinear coefficients of KNbO3, KTiOPO4, KTiOAsO4, LiNbO3, LiIO3, β-BaB2O4, KH2PO 4, and LiB3O5 crystals: A test of Miller wavelength scaling

Alford, William J.; Smith, A.V.

The wavelength variation of the second-order nonlinear coefficients of KNbO3, KH2PO4 and LiB3O5 crystals was discussed. The second-order nonlinear coefficients were measured using optical parametric amplification and second-harmonic generation over a wide range of wavelengths for the crystals. The results showed that Miller scaling was a useful approximation for the crystals.
