Multiple reflections and Fabry-Perot interference corrections in Maker fringe experiments

Measurements of nonlinear optical coefficients of frequency doubling proces ses can be done by using the Maker fringe technique. For relative measureme nts this technique offers high accuracy and reliability. To assure an accur acy of a few percent, effects of multiple reflections and Fabry-Perot inter ferences have to be taken into account. We derive an analytical formula for correcting these effects, because both effects strongly interact with each other. In our formula the effective Fabry-Perot terms can be weighted. The results are compared to measured data. (C) 1999 Elsevier Science B.V. All rights reserved.
