Growth and characterization of nonlinear optical crystal BaCaBO3F

Colorless and transparent BaCaBO3F single crystals were grown by employing the Kyropoulos method. A well-developed morphology of BaCaBO3F crystals is observed, but it differs depending on the growth direction. Differential scanning calorimetry analysis showed that BaCaBO3F crystal melts congruently at 1083.4 °C. The optical transmission spectrum of the BaCaBO3F crystal was measured at room temperature, and it was found to be transparent in the 220–2500 nm wavelength range.
