We strive to explore and understand a broad range of physical phenomena induced by ultrashort laser pulses with materials of different kind. We are seeking for innovative science concepts in the research areas of laser-matter interaction physics, which would advance design of functional surfaces, synthesis of nanomaterials and nanostructures with novel properties, creation of new photonic structures, and bio-applications. The team combines experimental studies with state-of-the-art diagnostics techniques and a strong theoretical expertise in the areas of laser excitation of solids, phase transitions, dynamics of the laser-induces plumes.
We are building an advanced laser application laboratory, which will include three ultrashort pulse lasers with laser wavelengths from UV to mid-IR, high-vacuum chambers, time-of-flight mass spectrometry, ultrafast diagnostics (pump-probe techniques, streak camera, ICCD imaging, LIBS) and material characterization (optical microscopy, SEM, XRD, AFM, Raman).
The theoretical support of the experiments is based on the experience of team members in
- one- and two-temperature modeling, including electron photoemission with charge separation and non-congruent vaporization of compound materials;
- FDTD simulations of propagation of laser beam focused inside transparent materials;
- gasdynamic modeling of laser ablation plume expansion in vacuum and ambient gases;
- TD-DFT simulations of laser action on band-gap crystals;
- analytical methods of plasma physics and plasmonics.
Prestigious Fellowship for Dr.Yury Ryabchikov
Dr. Yury Ryabchikov, a researcher from the HiLASE Centre, has been granted a prestigious Marie Skłodowska-Curie Individual Fellowship in the framework of Horizon 2020 programme of the European Commission. The main aim of his project entitled “LAser DEvelopment of Nanotools for quantum-based THERapy (LADENTHER)” is to explore laser-synthesized multi-component nanoparticles with novel properties activated by ultrafast mid-infrared laser as possible agents for bio-medical applications.
Patent for highly-regular laser-induced periodic surface structures
In collaboration with the University of Modena and Reggio Emilia, Italy, the formation of highly-regular laser-induced periodic surface structures (HR-LIPSS) has been achieved on metal surfaces at record writing speed. The theory has been developed which explains, describes and predicts LIPSS regularity based on metal optical properties and irradiation conditions. This work is protected by the patent of Czech Republic No. PV 2016-424
International Application No. PCT/CZ2017/050027.
Mass Spectrometric System for Studies of Laser-Matter Interaction Processes
Prof. Alexander Bulgakov, Dr.Sc. and Oleksandr Gatsa, PhD, from HiLASE Centre SLA department have introduced a mass spectrometric system for studies of laser-matter interaction processes. The system consists of three main parts: large laser ablation vacuum chamber, high-resolution time-of-flight mass spectrometer, an instrument for studying these processes, and an intermediate separately pumped vacuum chamber between the ablation chamber and the MS.
Patent: A method and a device for assembly of a nanomaterial structure
The present invention relates to a method and device capable to form a nanomaterial structure on a receiver by transfer of nanomaterial from a donor film. In some embodiment, the transfer can be provided by laser induced forward transfer, more preferably by blister based laser induced forward transfer.
