title: Sellmeier equations and phase-matching characteristics of the nonlinear optical crystal RbBe2BO3F2.
abstract: We have successfully grown a new nonlinear optical crystal, RbBe2BO3F2 (RBBF), which belongs to the group of borate-based nonlinear optical crystals. Its refractive indices in the visible spectral region and type I phase-matching angles from the deep ultraviolet to the near infrared have been determined. Based on the measured refractive indices and phase-matching angles, the Sellmeier equations of RBBF have also been derived.
