The refractive indices of Li2B4O7 crystal were measured for both ordinary and extraordinary beams in the range of 184.887 nm-2325.42 nm, and the Sellmeier equations were derived from these results. Li2B4O7 crystal has a suitable phase-matching condition in the ultraviolet range and the shortest SHG output wavelength of 243.8 nm. Considering also its short-wavelength cutoff and low scattering, Li2B4O7 crystal is an excellent nonlinear optical crystal for an ultraviolet solid-state laser.
