Comprehensive analysis of multiple-reflection effects on rotational Maker-fringe experiments

What we believe to be a new mathematical procedure has been proposed for analyzing the rotational Maker-fringe data taking account of the effects of multiple reflections and interferences of the fundamental and second-harmonic beams in anisotropic plane-parallel plates. In the present formalisms partial overlaps of the fundamental and second-harmonic beams are fully included. A comparison between numerical simulations based on the proposed formalisms and experimental data obtained for a high-quality (0001) plane-parallel plate of 6H-SiC revealed the validity of our theory. We have determined the magnitudes of the nonlinear optical coefficients of 6H-SiC as d(31)=d(32)=6.7 +/- 0.8 pm/V, d(15)=d(24)=6.4 +/- 1.1 pm/V, and d(33)=-9.7 +/- 8.0 pm/V.
