Optical quality characterization of KDP crystals with incorporated TiO2 nanoparticles and laser scattering experiment simulation

We study the elastic scattering of light in pure KDP crystals and KDP crystals with incorporated titanium dioxide nanoparticles. It is shown that the optical quality of the crystals decreases insufficiently for the used concentrations of nanoparticles. A mathematical model of the experimental setup for light scattering measurements in low-dispersion media is developed and discussed. The propagation function of the experimental setup is given in analytical form. The relevance of the model is verified with the use of experimental scattering data.
