Abstract
For ultraviolet (UV) nonlinear optical (NLO) crystals, three fundamental parameters are essential: the absorption edge, the NLO coefficient, and the shortest wavelength for second harmonic generation (SHG) phase matching (PM). In this study, a rare-earth borate, Rb 7 PbY 2 (B 5 O 10 ) 3, was synthesized via chemical cosubstitution using a high-temperature melt method. Rb 7 PbY 2 (B 5 O 10 ) 3 has been found to crystallize with a noncentrosymmetric (NCS) space group and has an SHG intensity of 1.3 times KDP and a UV cutoff edge of less than 300 nm. These properties indicate that Rb 7 PbY 2 (B 5 O 10 ) 3 exhibits significant potential as an NLO material.
