Lab team

The International Laboratory of Femtosecond Optics and Femtotechnology at ITMO University was established in 2013 with the support of the 5-100 program (the Program to increase the competitiveness of ITMO University among the world's leading scientific and educational centers for 2013-2020).

Over the past five years, the laboratory has been conducting theoretical and numerical studies of nonlinear and linear properties of materials, phenomena arising under the action of femtosecond and terahertz pulses, as well as conducting their experimental verification.

The laboratory is actively developing a direction in the field of optical information transmission, within the framework of which new physical principles of transmission using quasi-discrete spectral supercontinuums are proposed. Using equipment for pulsed terahertz spectroscopy with the possibility of registering a terahertz field, a number of experiments were carried out on the generation and control of polarization of terahertz radiation with two-color filamentation, on characterization of the properties of individual biological materials. The laboratory also conducted a number of experiments in the field of nonlinear femtosecond optics, such as measuring the nonlinear refractive index of materials, measuring the generation of the third harmonic in metamaterials with silicon nanoparticles.

The laboratory team includes a strong theoretical group. Work is underway in related areas, namely: generation of THz radiation from solid-state materials, two-dimensional materials and filamentation in air, terahertz spectroscopy with time resolution, propagation of high-intensity terahertz and optical waves in nonlinear media. The results of work in the field of femtosecond and terahertz optics of the international laboratory have been published in more than 100 scientific articles, including many highly rated journals.
