Workshop on Laser Fusion, a spin-off from heavy-ion collisions

Talk

Laser induced Inertial Confinement Fusion has many new ideas recently. In the NAPLIFE project our aim is to circumvent some of these by results from ultra-relativistic heavy ion reactions and nanotechnology. We aim for time-like detonation to avoid instabilities and slow spreading of the burning front and regulate the light absorption in the target by implanted nano-antennas. The initial...

Lecture

Recently laser induced fusion a spin-off from heavy ion collisions was proposed, where implanted nanoantennas regulated and amplified the light absorption in the fusion target [L.P. Csernai et al., Physics and Wave Phenomena 28 (3), 187-199 (2020)]. The theoretical part in this kind of experiments is powered by plasma simulations, here, we will present the behaviour of nanoantennas built in a...

The presentation discusses various aspects of Laser Induced Breakdown Spectroscopy(LIBS), an emission spectroscopic technique used for elemental analysis. It focuses on the interaction of a femtosecond laser with a pulse duration of 50fs and repetition rate of 10Hzwith the polymeric composition of Urethane Dimethacrylate(UDMA) and Triethylene Glycol Dimethacrylate(TEGDMA), as well as UDMA...

Talk

The effects of gold nanorod doping and high intensity laser irradiation on the structural and the morphological changes of the urethane dimethacrylate (UDMA) based polymer systems were investigated and characterized using scanning electron microscopy (SEM) and Raman spectroscopy.
UDMA polymer samples with different concentration of gold nanoparticles were illuminated by single shot...

107. Effect of the embedded plasmonic gold nanorods on the interaction of high intensity laser irradiation with UDMA polymer – the volume loss during crater formation

Talk

In this work we studied the effect of the addition of gold nanoparticles to urethane dimethacrylate (UDMA) polymer on the crater formation during high intensity femtosecond laser irradiation.
UDMA polymer samples were prepared without gold nanorods and with those in two different concentrations and were irradiated in different spots with single femtosecond laser pulses of different energies....

Talk

Raman spectroscopy is widely used to characterize different materials through the vibrations of their constituents. It is highly sensitive to changes in bonding configuration, crystalline structure, isotope content, or even internal stress. We report on Raman spectroscopic studies of structural transformations in urethane dimethacrylate/triethylene glycol dimethacrylate copolymer nanocomposite...
