Experimental reconstruction of a nonlocal nonlinear response function of a thermal medium

We present a novel experimental technique for retrieving the spatial profile of a nonlocal response function in a medium with thermal nonlinearity. Our method is based on the quantitative measurement of the light-induced nonlinear phase distribution by holographic interferometry combined with an iterative process of two-dimensional deconvolution using the known pump beam intensity distribution.
