Automated complex for the investigation of the optical limiting and nonlinear light scattering by the z-scan technique

An automated Z-scan technique hardware-software complex to study the optical power limiting and nonlinear light scattering in materials is designed and fabricated for the first time. In a single pass z-scan it allows us to produce the curves indexes characterizing nonlinear absorption, nonlinear refraction and nonlinear scattering automatically. The complex operates by the specially developed control software, which allows to carry out high precision studying of nonlinear interaction between the laser radiation and the sample in different regimes and flexibly to change the course of the experiment. The efficiency of the complex demonstrated by the study of the optical power limiting in suspensions of detonation nanodiamonds.
