A Modified‘Position Dispersion’Method for Nonlinear Refraction Index Measurement

         

摘要

In this report,a modified‘position dispersion’method,in which the detecting aperture in the far-field is replaced by a circular board,is given to enhance the measurement sensitivity of nonlinear index,while keeps the simplicity.An increase of 5 times in sensitivity is obtained in our experiment,in which we employed a solution to produce the thermally induced nonlinearity.
