Paper Abstract

We present a theoretical and experimental analysis of the Z-scan technique in thick media with thermal nonlinearity in steady-state regime. The theoretical model considers the thick medium as a stack of thin thermal lenses. Numerical solution for the Z-scan technique is obtained. Experimental results for the technique using a sample of methylene blue in a solvent under cw illumination from a 10 mW He-Ne laser beam are obtained. Comparison of the experimental and theoretical results is made. Good agreement between theory and experiment is obtained.
