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.

Laser is suitable for nanophotonic 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.
