Abstract

Accurate index of refraction measurements have been performed in flux-grown KTiOPO₄. These measurements give good agreement between experiment and theory for angle phase matching in Type II second harmonic generation at 1.064 μm. These refractive-index data have allowed us to calculate the propagation angles for second harmonic generation at wavelengths of interest other than 1.064 μm such as 1.34 μm. Type II second harmonic energy conversion efficiency of 1.064 μm of up to 59% in this material has also been demonstrated with higher efficiencies possible. Limits to conversion efficiency are discussed.
