title: Determination of the nonlinear optical coefficients of the BaGa(4)Se(7) crystal.
abstract: The second-order nonlinear optical (NLO) coefficients of the BaGa(4)Se(7) crystal were experimentally determined through the Maker Fringe Technique for the first time. The values of the two major nonlinear tensor elements d11 and d13 were 24.3 and 20.4 pm/V, respectively. These results were in agreement with the ones obtained through theoretical calculations.
