HPLA TOPICS

Fundamental Physics and Simulations of Laser-Materials Interactions
This session will focus on recent advances in fundamental understanding of laser-material interactions that emerge from computer modeling and experimental probing of laser induced processes. The transient atomic dynamics and electronic phenomena in photo-excited materials as well as the longer-term structural and thermodynamic material response to the laser excitation will be discussed. The new physical insights revealed in electronic structure calculations, large-scale atomistic simulations, and hydrodynamic modeling of laser interactions with metals, semiconductors and insulators will be presented

Nanoengineering and Material Processing
This session is devoted to novel laser-based Nanoengineering and Material Processing technologies and their applications. At present, laser direct-write and additive manufacturing are becoming important industrial technologies. It remains challenging to improve their resolution limits and to apply these technologies at the nanoscale. Nanoengineering with lasers allows getting better understanding of basic physical and chemical processes involved in laser material processing and generates exciting applications in photonics, microfluidics, and biomedicine.

Biological Applications

This session is dedicated to the use of modern laser technology for improved biomedical research. Recent growth in the applications of lasers to medicine and biology has been explosive. The objective of the session is to bring together international researchers to jointly examine how new laser technologies have provided new knowledge in biology, and pave the way for innovative medical procedure developments. HPLA attendees will have the chance to critically assess the state of the biological application of lasers and to set goals for the future

Promising New Laser and Optical Technologies
This session will address promising laser and optical technologies for various applications such as flexible microelectronics, biocompatible materials, renewable energies or metamaterials. Distinguished international speakers will present the creation of active color filters with metal nanoparticles, the hydrodynamics of microfluids for laser printing (LIFT), the origin of the nanostructures created by fs lasers on solid surfaces, how to create structures on solar cells using laser interferences, and how to use lasers to create new 2D and 3D metamaterials…

Just before the session, Prof. Eric Mazur (Harvard University) will give a Keynote lecture " Ultrashort Lasers to Increase Efficiency in Solar Energy Harvesting via Intermediate States".

Fundamentals/Simulations
This session is concerned with material properties during and after ultrashort laser irradiation. Molecular dynamic approaches address questions of anharmonic lattice dynamics and coherent phonon decay, as well as the influence of the pulse shape on ablation threshold. Ab initio calculations and comparisons to experiments highlight electronic properties of matter as the electron heat capacity, electron-ion coupling factor and AC conductivity, as well as structural changes due to ultrafast excitation.

A two-temperature model combined with molecular dynamic simulations will be presented, while the concept of temperature will be critically discussed by modelling nonequilibrium electron systems, providing the range of applicability for temperature-based descriptions. Studies of warm dense matter, a state passed during laser ablation, reveal modifications of microscopic parameters as compared to solids or hot plasmas. The relevance for thermodynamic and relaxation properties as well as heat and charge transport will be discussed.

The session will cover problems related to the material phase and morphology modifications and imaging/probing of processes with high spatial and temporal resolutions. The relevant processes can be triggered with a strong localized energy deposition from femtosecond UV-visible and extreme-UV laser sources and include ultrafast (charge carriers excitation, carrier-lattice exchange, energy transport) and slower (melting, hydrodynamics, re-solidification) phenomena that affect and define the irradiated surface morphology and structural properties. The experimental methods and theoretical approaches will be discussed. The progress in the field opens possibilities for mapping the chemical composition and process control with unprecedented resolution and sensitivity.
