This paper reports the growth and spectral properties of Er³⁺/Yb³⁺:LaCa₄O(BO₃)₃. The Er³⁺/Yb³⁺:LaCa₄O(BO₃)₃ crystal with diameter 30mm and length 40mm was obtained using the Czochralski method. The absorption and emission spectra of Er³⁺/Yb³⁺:LaCa₄O(BO₃)₃ crystal have been investigated. The strong absorption band with absorption coefficient 13cm⁻¹ at 900–1050nm was observed in Er_0.05/Yb_0.5:Ca₄La_0.45O(BO₃)₃ crystal. The emission band in 1510–1580 was observed, and its fluorescence lifetime is about 1.22ms at 300K.
