Research and services are carried out by using:
1. Light conversion femtosecond laser system Pharos. 6W average power diode-pumped high repetition rate femtosecond Yb:KGW laser. Maximum repetition rate is 200 kHz. Central wavelength 1030 nm, pulse duration 300 fs, pulse energy to 0.4 mJ.
2. Precision three-coordinate positioning system with a galvanometric beam control subsystem.
3. Technological system for polymeric layers formation and processing.
4. Electronic microscope TM-1000.
5. Unique set of equipment and diagnostic for nanophotonic system.
Application. Laser nanophotonics research:
1. Numerical modeling, laser formation, geometry and optical properties (focus, collimation, phase modulation) description of multifunctional (refractive / diffractive) and integrated (on the optical fiber tip) micro – optical elements (10 – 100 μm).
2. Artificial three-dimensional frames laser formation for cell biology and tissue engineering applications. There is a possibility to use biologically inert and degrading polymers and to produce carcass made of several different materials. Pore size and filling factor can be varied from 1 to 100 μm and 20-80%, respectively.
3. Laser formation of nanophotonic elements in polymers and transparent material. It is a possibility to form with laser two-dimensional and three-dimensional fixed and gradually variable period photonic crystals. Their period can be from 0.5 to 10 μm. Numerical modeling of these items and characterization of their light control properties.
