Special session
The demand for accuracy in laser material structuring is pushing forward for processing technologies which require matter and shape adaptability. Programmable tailoring of laser pulse intensity envelopes offers the possibility to regulate and self-improve the energy delivery in a synergetic manner. This creates the premises to upgrade the degree of process control, opening new areas of investigation that span from basic science to innovative manufacturing technologies. This session will focus on examination of several perspectives on the process of material modification and associated laser processing technologies including the potential of designing excitation geometries or controlling laser-induced physical phenomena. Original papers are solicited showing progress towards the developments of manufacturing technologies capable of offering high degree of precision and efficiency.
Lasers are widely used for processing and manipulation of cells, biological tissues and biocompatible materials on an ever finer scale and with increasing throughput. Novel techniques include the optical trapping, sorting, dissection, transient permeabilisation, and transport of cells, the procurement of defined samples of histologic materials for proteomic and genomic analysis, dissection and precise ablation of tissues, and laser-based preparation of biomolecules for subsequent mass spectroscopy. Nanoscalpels can be realized using tightly focused trains of ultrashort laser pulses, or by irradiation of entire cells with targeting through antibody-conjugated absorbing nanoparticles (NPCS) or fluorophores (CALI). Biological reactions are triggered by localized laser irradiation and monitored by laser-based microscopy. Papers are solicited on, but not limited to, the following topics: Laser ablation, nanosurgery, manipulation, and transport of biomolecules, cells, and tissues, investigations on fundamental aspects of the laser-biomaterial interaction, plasmonic laser nanosurgery, diagnostics and on-line control for in situ laser microprocessing, Laser-assisted mass spectroscopy, laser applications in microfluidic and lab on a chip devices, and medical laser applications.
Laser micro processing and surface functionalisation becomes increasingly important in industry not only for small products but also for large components, where specific advantages of laser processes offer new manufacturing methods with decreased thermal influence and very selective change of material properties. This special session will be dedicated to large scale micro processing for various industrial applications, including photovoltaics, printing industry, OLED and display manufacturing, high speed micro drilling, surface structuring on large components, microstructures for improved wear resistance. Contributions should address likewise new laser processing approaches for high speed manufacturing as well as necessary equipment and laser sources.
