Crystal Growth and Associated Properties of a Nonlinear Optical Crystal—Ba2Zn(BO3)2
Abstract
Crystals of Ba2Zn(BO3)2 were grown by the top-seeded solution growth (TSSG) method. The optimum flux system for growing Ba2Zn(BO3)2 crystals was 2BaF2:2.5B2O3. The transmission spectra of a (100)-orientated crystal indicated an absorption edge of 230 nm. Powder second-harmonic generation measurement revealed that Ba2Zn(BO3)2 can achieve type-I phase matching behavior at the fundamental wavelengths of 1064 and 532 nm respectively. The second-harmonic generating efficiency is around 0.85 and 0.58 times that of β-BaB2O4 when radiated with 1064 and 532 nm lasers.
