This paper reported the crystal growth and spectroscopy characters of Cr³⁺: Li₂Mg₂(MoO₄)₃. The refractive index of Cr³⁺: Li₂Mg₂(MoO₄)₃ crystal is 1.87 and the hardness is 270 HV. This crystal shows broadband absorption property with peak wavelength at about 495 and 699 nm. The absorption crosssection is 14.75×10^-20 cm² at 495 nm and 9.63×10^-20 cm² at 699 nm, respectively. The crystal field strength and energy levels of Cr³⁺ ion were calculated based on the spectroscopic data. The Cr³⁺: Li₂Mg₂(MoO₄)₃ crystal shows broadband emission extending from 750 to 1300 nm even excited at 10 K. The room temperature emission cross section is 72×10^-20 cm² at 926 nm. A discussion of the relation between the spectroscopic properties and crystal field parameters of Cr³⁺: Li₂Mg₂(MoO₄)₃ crystal was presented based on the solid state spectroscopy theory.
