The Department of Laser Systems and Physical Technologies has extensive contacts with its counterparts both in Ukraine and abroad. In cooperation with partners, joint research is carried out, specialists of different levels are trained, national and international conferences are held.

The beginning of international cooperation of the Department of Laser Systems and Physical Technologies dates back to the 70s of the last century. Due to the annual international scientific conferences on laser technology and other non-traditional materials processing technologies, the department's contacts with universities and enterprises of the USA, Japan, Great Britain, Canada, Germany, Portugal, the Czech Republic, China, Taiwan and others have expanded.

For many years, fruitful cooperation has been established between the faculty and colleagues from the University of Jena, the University of Birmingham, the University of Osaka, the University of Ohio, and others like that. With lectures to students and lecturers, prominent experts from different countries of the world: prof. Bill Stin (Liverpool University, UK); Academician of the Academy of Sciences of Japan, prof. Yeshiaki Arata (Research Institute of Welding, Osaka University, Japan); prof. Franz Schiffer, Dr. Gisbart Stauppendal (University of Jena, Germany); Dr. Lyubomir Romankov (company IBM, USA); prof. Charles Albright (University of Ohio, USA), Dr. Jan Spalding (UK) and others.

The staff of the department participated in various international congresses, symposiums, conferences: ICALEO - International Conference on Appliances of Lasers and Electro-Optics, ISEM - International Symposium on Electromechanics, LAMP - Laser Applicatio for Materiel Processing, General Assembly of the CIPP (International Institute of Manufacturing Engineer). The recognition of the world's achievements in the field of laser technology became the election in 1993 of a professor. Kovalenko as Distinguished Visiting Professor of the State University of Ohio (USA), where he taught during the 1994 semester.

In 1996, professors Kovalenko and Golovko were invited by the Laser Institute of America to the International Publishing Board (International Editorial Board) to prepare the International Laser Handbook, Magnolia Publishing Inc., Orlando, Florіda, USA, in which they became the authors of the eight sections of this unique edition.

On August 30, 2008, in Manchester at the final session of the General Assembly of the CIPP, prof. Kovalenko was elected a full member (Fellow).

Since 2005, cooperation with Chinese colleagues from Zhejiang University has begun. During the years of close and fruitful cooperation, various processes of laser processing of materials were investigated, scientific and technical information exchange and specialists were exchanged.

The main object of the research was the creation of a modern technology for the restoration of components of complex equipment based on the development of a modern robotic laser complex with a powerful diode laser and the transport of laser beam with fiber optic cable. Due to the use of this complex, the processes of laser strengthening of the surface of products, surface alloying of metal alloys, laser surfacing, laser-layer grooving of three-dimensional products, welding of various alloys, etc. were investigated. Methods for mathematical modeling of various processes have been developed to select optimal processing conditions, which has allowed to significantly improve the efficiency of processes and reduce the duration of the choice of processing modes. The technological processes of microprocessing of precision products, in particular, medical cardio endoprostheses, were also explored and developed.
