Abstract
Large single crystals (60×20×8 mm3) of a new nonlinear crystal thienylchalcone (T-17) were grown from acetone by the falling temperature method and the nonlinear optic properties were determined. The effective nonlinear optical coefficient, the angular acceptance (Δθ,Δφ), and the walk-off angle were 7.1 pm/V, 0.053° cm, 1.2° cm1/2, and 3.6°, respectively. Thienylchalcone could be type-I phase matched for the light of wavelengths longer than 910 nm. It is an attractive nonlinear crystal for generating green and blue lasers.
