Abstract

A new beryllium-free deep-ultraviolet (DUV) nonlinear optical (NLO) material, β-Rb2Al2B2O7 (β-RABO), has been synthesized and characterized. The chiral nonpolar acentric material shows second-harmonic generation (SHG) activity at both 1064 and 532 nm with efficiencies of 2×KH2PO4 and 0.4×β-BaB2O4, respectively, and exhibits a short absorption edge below 200 nm. β-Rb2Al2B2O7 has a three-dimensional structure of corner-shared Al(BO3)3O polyhedra. The discovery of β-RABO shows that through careful synthesis and characterization, replacement of KBe2BO3F2 (KBBF) by a Be-free DUV NLO material is possible.
