Abstract

Single-domain crystals of MTiOAsO₄, where M equals K, Rb, & Cs were grown from various alkali arsenate self fluxes. Their refractive indices and Sellmeier coefficients were determined with critical angle of total reflection measurements. Type-II phase-matched SHG was used to check for crystal domains and to determine the accuracy of the Sellmeier coefficients. The d_ij coefficients for second harmonic generation were determined with Maker-fringe technique at 1.06 micrometers . Electro-optic coefficients r_ji were determined with interferometry. This paper reports the above measurement results and discusses the systematics of crystal structure, birefringence, and optical nonlinearities among the pure isomorphs and their solid-solutions. Calculated SHG cut-offs and tuning curves are also reported.
