System is suitable for 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 frame laser formation for cell biology and tissue engineering applications. Biologically inert and degrading polymers can be used, and a carcass can be produced of several different materials. The 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. Two-dimensional and three-dimensional fixed and gradually variable period photonic crystals can be produced with the laser. Their period can be from 0.5 to 10 μm. Numerical modeling of these items and characterization of their light control properties.
