Abstract

Centimeter-sized Bi2ZnB2O7 (BZBO) and Nd:Bi2ZnB2O7 (Nd:BZBO) single crystals are grown using the Kyropoulos method. The thermal properties and continuous wave (CW) laser performance are investigated. Results show that the BZBO crystal possesses moderate specific heat (0.62 J g−1 K−1 at 20 °C), small thermal expansion (α11 = 6.9 × 10−6 K−1, α22 = 11.2 × 10−6 K−1 and α33 = 1.9 × 10−6 K−1 at 20 °C) and large thermal conductivities (4.3, 3.2 and 4.0 W m−1 K−1 along the crystallographic a-, b- and c-axes at 25 °C, respectively). Moreover, the CW laser tests are realized at a wavelength of 1.06 μm for the Nd:BZBO crystal (0.5 mol% Nd3+), and the output powers are found to be around 256 mW, 235 mW and 312 mW along the optical X-, Y- and Z-orientations, respectively. Nd:BZBO might be another kind of important laser and nonlinear optical crystal in the oxyborate family.
