AB  - Nuclear fusion (NF) as a source of clean energy is of interest to many governments, research groups, etc., nowadays. In order for NF to be applied in full capacity, certain problems related to plasma physics and reactor technology should be overcome [1]. In the main, there are two approaches at this moment, the first one based on magnetic confinement and the second one based on inertial confinement fusion, i.e. laser concept. Focusing only on the reactor technology, it is of high importance, among other, to apply the reactor materials (RM) possessing high resistance to thermal and radiation (including electromagnetic) flux [2]. In this context, the behavior of fusion RM, particularly potential plasma facing materials (PFM), will be observed. In nuclear reactor, the PFM are exposed to various fluxes such as the neutrons, alfa-particles, electromagnetic, thermal, hydrogen isotopes. These high thermal as well as electromagnetic fluxes can be, in one approximation, simulated by high-intensity laser radiation [3, 4]. Examples of high intensity femtosecond laser – material interaction will be presented in this work. The materials, i.e. candidates for PFM like tungsten, oxide dispersion strengthened (ODS) steel, will be investigated under the action of high laser intensity of the order of 1014 W/cm2  [5, 6]. Also, the presence of hydrogen isotopes in PFM will be analyzed.

AB  - The behavior of 16Cr3Al ODS steel (oxide dispersion strengthened steel), widely employed structural fusion material, under high-intensity laser radiation with intensity up to 10(14)W/cm(2) was investigated in air, helium and vacuum surrounding. Employed system was 65 fs laser at 804 nm, with applied pulse energy up to 5.25 mJ. Morphological effects were studied - cracking, crater parameters (depth, cross-section), LIPSS (laser-induced periodic surface structures) formation at the crater periphery, hydrodynamic effects, as well as chemical variations on the surface. Ablation thresholds were also determined for all three ambiences (for 100 applied pulses), and they were 0.30 J/cm(2), 0.23 J/cm(2) and 0.39 J/cm(2) in air, helium and vacuum, respectively. Plasma occurred in all experiments and it was most prominent in vacuum due to strongest laser-material coupling.
