News del 08/03/2011Low-threshold ablation of dielectrics and metals irradiated by ultrashort pulses of soft X-ray transient-collisional and free electron lasers
      Recent results of experimental and theoretical studies of ablation of condensed matter by soft X-ray transient-collisional and free electron lasers will be presented. A very low ablation threshold of LiF crystals ~ 10 mJ/cm2 was determined for both types of lasers irradiation. This is substantially below the ablation thresholds obtained with other lasers having longer pulse duration and/or longer wavelength. Such low ablation threshold was explained in the frame of photo-thermo mechanical theory consideration. It was also experimentally shown that ablated mass of dielectric with strong growth of laser fluency in the case of XRL has slow growth. A theory is presented which explains this result as the transition from spallative ablation near threshold to evaporative ablation at high fluencies. It was also demonstrated that when aluminum surface of solid target was irradiated by the fluencies of up to 27 mJ/cm2 thhe surface modifications caused by the SXRL pulses were clearly seen, and it was found that the conical structures having about 70–150 nm in diameters were formed under a single pulse shot. The conical structures were formed in the features with the average depth of about 40 nm, and this value was in accordance with the attenuation length of the SXRL beam for Al. Thermo-mechanical modeling of SXRL laser interaction with Al surface, which explains nanostructure surface modification, will be provided. All obtained results clear demonstrated that ultrashort soft X-ray laser irradiation of different materials could be used for micromachining of different materials

News del 08/03/2011Pulsed Laser Ablation in Liquid (PLAL) for Nanoparticle production
      The interest in nanosized particles (NPs) has hugely grown because of their peculiar physical and chemical properties related to quantum size effects with respect to bulk samples and to the enhancement of surface properties due to the large surface/volume ratio. In the past decade, a large part of the scientific effort was focused on the setup of techniques and methodologies of NP synthesis that allow adequate control of particles size distribution, shape, and crystallinity, adequate temporal stability, and, at the same, a production rate sufficiently high for real applications and industrial scale-up. In recent years, Pulsed Laser Ablation in Liquid (PLAL) was introduced as a production technique and tested for different composition NPs, including metals, semiconductors, carbon-based nanomaterials and alloys. In the PLAL technique, a laser pulse is focused on a target immersed in a solvent generating a microplasma that rapidly expands, quenches, and decays in times on the order of microsecond. During such a process, the atomized material removed from the target, interacting with the species originated from the solvent, nucleates and begins to grow up to the formation of NPs. The talk will include an introduction to the technique, including a discussion about its advantages with respect to the most used chemical methods, its current drawbacks and limits, as well as possible research routes for improving the state of knowledge of the process and the control of produced NPs.

News del 08/03/2011Relativistic Mirrors in Laser Plasmas – a Path towards Compact Source of Coherent X-Rays
      Abstract: In laser plasmas, the relativistic flying mirrors are thin and dense electron or electron-ion layers accelerated by the high intensity electromagnetic waves up to velocity close to the speed of light in vacuum. The reflection of the electromagnetic wave at the relativistic mirror results in its energy and frequency change due to the double Doppler effect. This scientific area promises the development of the sources of ultrashort x-ray pulses with the parameters required for studying of complex structures in nanometer scale and in attosecond range.
