Abstract
Large (5 × 3 × 3 cm3) crystals of the organic nonlinear optical material MBA-NP have been prepared by growth from solution, in an optically and structurally highly perfect state. Oriented cut and polished specimens were examined by the Maker fringe technique at a wavelength of 1·064 µm. Analysis of the data yielded d 22 as 69 × d11 quartz with a corresponding coherence length of 2 µm. A large rotation of the X and Z dielectric axes with wavelength (30° over 200 nm) was observed. Type I phase-matched second-harmonic generation (SHG) was recorded. For the 1·064 µm dielectric axis set and a (010) faced crystal, phase matched SHG was observed for rotation about X to an angle of incidence of 45°. This angle is very sensitive to the correct alignment of dielectric axes and the effect of its misalignment was investigated.Keywords
