文摘Considering that KBe2BO3F2(KBBF) is an outstanding deep ultraviolet crystal which can generate the shortest wavelengths in second harmonic generation and sum-frequency generation,we report the determination of the nonlinear optical coefficients of the KBBF crystal.The d11 coefficient was determined to be 0.49pm/V by the Maker fringes method at the wavelength 1064nm,which is in agreement well with the theoretical value.
