Abstract
KTb3F10 (KTF) crystal, characterized by its high Tb 3+ ion concentration, low thermo-optic coefficient, and low phonon energy, demonstrates significant potential for efficient laser emission in the green and yellow wavelength ranges.However, challenges such as incongruent melting behavior, hygroscopicity of raw materials, high-temperature compositional volatility, and the corrosive nature of fluorides have severely hindered the growth of high-quality KTF crystals.This study aims to develop an effective approach to address these issues, achieve the growth of high-quality KTF crystals, and systematically characterize their optical properties.An optimized vertical Bridgman method integrated with a laser-sealed platinum crucible technique under vacuum was employed.This innovative approach effectively shielded the raw materials from water and oxygen contamination while suppressing compositional deviation during crystal growth through a sealed environment.As a result, blank KTF crystals with dimensions of 16 mm 30 mm were
