AB  - Behavior of ODS steel under high energy fluxes is important as it is one of the most promising fusion reactor materials. The addition of hafnium provides improved microstructure and therefore better mechanical properties at high temperatures, and the goal here was to investigate the effects induced on Hf-containing ODS steel by the action of high-intensity ∼1015 W/cm2 radiation obtained by ultrashort pulsed laser. Morphological and chemical parametric study of the surface was conducted at different work ambiences. New data were obtained on damage parameters, threshold fluences and chemical changes. Measured damage depths were ∼7.5 μm (air), ∼14 μm (helium), ∼48 μm (vacuum), which is somewhat lower compared to ODS steel without the addition of hafnium.

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.
