The aim of the project is to create conditions for internationally high value-added scientific results and to provide high-scientific services in the research of ultrashort light pulse generation in a wide range of waves and their application in radiation-substance interaction, nonlinear optics and parametric phenomena, ultra-fast processes, and laser nano- and microtechnology. The research infrastructure for high-intensity and wide-wave ultra-short laser pulses of national and international access combines VU LTC and FTMC LTS units, which successfully develop both fundamental and applied scientific themes for the development and application of ultra-short pulse lasers. Global trends in the development of laser technologies dictate new needs for laser technology science, but the application of some advanced laser technologies due to their complexity and cost is only possible in large national and international laboratories. ELI-DC is important for the Lithuanian laser sector, which combines three of the final construction and installation of very high-value specialised ELI MTIs located in the Czech Republic, Hungary and Romania. Eli aims at new fundamental studies of extreme intensity of light in interaction with material, high temperature plasma physics, acceleration of electrons and ions in light fields, generation of resistive pulses and other high intensity light applications. Participation in ELI is particularly important for the Lithuanian laser sector, which will provide an opportunity to join the international community of scientists working with foreground knowledge and technologies, to influence the development of the centres and technologies applied in them in a direction that is beneficial to Lithuanian scientists. During the project implementation, equipment will be purchased for VU LTC and FTMC LTS Scientific Laboratories. Modernisation of the FTMC laboratory premises has also been carried out. The project will, among other things, aim at connecting to the international ELI infrastructure.
