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 (4F3/24 I11/2 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 ( 1D23H4 and 1G23H5 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.
