The article dwells on several issues connected with creating a research facility for investigating laser processing of materials. The facility is based on the Patara PA-016-QTG laser. Creating this research facility was connected with developing the visualization of systems controlling laser beam polarization in the process of laser cutting, and creating the complex equipment for illuminating the field of laser processing, and for preventing the unwanted effect of plasma on the processed surface. The concept solutions obtained in the development process are presented together with the author’s calculations and extracts from the technical documentation which appeared in the process of their production.
