Abstract

The investigated Bi₂ZnOB₂O₆ nonlinear optical single crystals doped with Nd³⁺ or Pr³⁺ ions were grown by the Kyropoulos method. Bi₂ZnOB₂O₆ single crystals doped with selected RE³⁺ ions are characterized by high values of nonlinear optical coefficients as well as the effective luminescence of excited RE³⁺ ions, which make this system a unique candidate for laser converters. The vibrational properties of Bi₂ZnOB2O₆:Nd₃₊ and Bi₂ZnOB₂O₆:Pr³⁺ single crystals were investigated with the use of μ-Raman spectroscopy. The strong emission of Bi₂ZnOB₂O₆:Nd³⁺ single crystals with maximum at about 1062 nm (⁴F_3/2→⁴ I_11/2 transition) was detected under the excitation at 514 nm. Emission spectrum of Bi₂ZnOB₂O₆:Pr³⁺ show enhancement of emission with maxima at about 1350 and 1470 nm ( ¹D₂→³H₄ and ¹G₂→³H₅ transition). The effective luminescence of excited Nd³⁺ or Pr³⁺ ions in Bi₂ZnOB₂O₆ single crystals as well as excellent nonlinear optical properties of Bi₂ZnOB₂O₆ host suggest that the investigated system can be very useful as a bifunctional crystals for new integrated optical systems such as self-frequency doubling lasers.
