The ability of Strontium Barium Niobate crystal as a two-dimensional nonlinear optical multiple-wavelength-and-direction converter is demonstrated, showing how harmonic generation can be obtained in an extremely large spectral range. The whole visible spectral region can be continuously generated without any angle or temperature tuning by using different nonlinear schemes involving SHG and THG in different configurations. The dominant frequency conversion mechanisms acting in each case are experimentally determined. The system can act as a nonlinear prism since the SHG conical radiation from 430 to 680 nm can be dispersed into an external angle range of 36°. Conical nonlinear processes are also demonstrated under intracavity conditions from a diode pumped Nd3+:SBN laser crystal. Different harmonic generated rings appear simultaneously inside the cavity, while the crystal is lasing at 1063 nm. The system constitutes the first experimental example of a two-dimensional generalized nonlinear photonic glass on a tunable solid state laser and can be useful for novel optical multifunctional devices such as nonlinear prism self-frequency converted solid state lasers.
