Abstract. KDP single and twin (prepared from two-glued seeds) crystals have been grown by the method of temperature reduction. Then, the grown crystals were cut and polished in the (100) direction for optical characterization. The transmission spectra and XRD analysis of the crystals were determined and compared. The Vickers microhardness tests carried out on the two types showed that duplication of the crystal lattice did not reduce the hardness of it.

Keywords: growth from solution, KDP crystal, nonlinear optical materials.
