Growth and nonlinear optical properties of K3B6O10Br crystal

Nonlinear optical (NLO) crystal K3B6O10Br with the size of 27×29 ×14 mm3 was successfully grown by top seeded solution growth (TSSG) technique. Its second harmonic generation (SHG) coefficients were determined by Maker fringe method as: d22=1.23±0.01 pm/V and d33=0.43±0.01 pm/V. Its linear electro-optical (EO) coefficient γ22=0.81±0.06 pm/V, which is usually employed in transverse modulation, was measured with polarimetric method.
