The recently developed nonlinear material, orientation-patterned gallium phosphide (OP-GaP), was characterized in detail by performing difference-frequency-generation experiments in the 2548-2782 nm wavelength range in the mid-infrared (mid-IR). This media file demonstrates the polarization dependent spatial beam shift observed in OP-GaP at 1064 nm. See J. Wei et al. Optical Materials Express 8, 555-567 (2018).
