We report on the phase-matching properties of borate crystals of LiB 3O 5 (LBO), CsB 3O 5 (CBO), and CsLiB 6O 10 (CLBO) in vacuum-ultraviolet (VUV) light generation at around 190 nm. A new phase-matching property in the VUV spectral range for CBO grown from a self-flux solution was found to have better agreement with new Sellmeier's equations developed in our laboratory. A 189nm output of 11.4mW was produced in a CLBO with a conversion efficiency of 7.3% from 213nm input. CLBO is suitable for VUV light generation around 190nm with the present laser system.
