Features of nonlinear optical properties of thin-film phthalocyanine coatings obtained by femtosecond hardware-software Z-scan measurement complex

In this paper, we study the nonlinear optical properties of thin-film phthalocyanine coatings based on the developed femtosecond hardware-software complex Z-scan. As a control of the complex, a combined system is used to ensure the synchronization of all components of the installation, as well as to automate the process of data collection and processing, which greatly simplifies the process of conducting the Z-scanning experiment. The results of measurement of nonlinear optical properties of the phthalocyanine thin films using femtosecond laser radiation are presented.
