Determination of the third-order nonlinear optical coefficients of germanium through ellipse rotation.
We describe the first reported direct determination of the 10 -Am nonlinear susceptibility in intrinsic Ge through time-resolved ellipse rotation. We found that X(3)(1111). = 2.5 X 10(-11) esu and X(3)(1221)= 1.3 X 10(-11) esu, significantly below previous estimates.
