Base on three wave coupled equations and energy conservation law, the frequency doubling properties of CsBe₂BO₃F₂ (CBBF) are analyzed theoretically at the first time. The phase matching angle, effective nonlinear coefficient, walk-off angle and permitted parameters are simulated in type I and type II phase matching. The difference of the CBBF optical properties between type-I and type-II are elucidated.: a wider phase matching range, a larger effective NLO coefficient and a smaller walk-off angle in range of 693.9~2730 nm in type-I were obtained. The properties of CBBF have been compared with the KBe2BO₃F₂ (KBBF) crystal. The larger lowest wavelength limit, smaller walk-off angles, a broader permitted angle and a larger peak value of the permitted wavelength of CBBF were proved.
