The International Laboratory of "Femtosecond Optics and Femtotechnology" of the ITMO University was established in 2013 with the support of the 5-100 program (ITMO University Competitiveness Program among the world's leading scientific and educational centres for 2013-2020).
Over the past five years, the laboratory has carried out theoretical and numerical studies of nonlinear and linear properties of materials, phenomena arising under the action of femtosecond and terahertz pulses, and also carries out experimental verifications in described fields.
The laboratory is actively developing the direction of optical transmission of information, within which new physical principles of transmission using quasi-discrete spectral supercontinuum are proposed. Using equipment for pulsed terahertz spectroscopy with the possibility of recording a terahertz field, a series of experiments have been carried out on the generation and control of the polarization of terahertz radiation in two-colour filamentation, on the characterization of the properties of biological materials.
The number of experiments in the field of nonlinear femtosecond optics was also conducted in the laboratory, such as measuring the nonlinear refractive index of materials, measuring the third harmonic generation in metamaterials with silicon nanoparticles.
The laboratory staff include not only experimentalists but also strong theoretical group.
Other research is underway in related directions namely, the generation of terahertz radiation from solid-state materials, 2D materials and in air filamentation, THz spectroscopy with a time resolution, the propagation of high-intensity terahertz and optical waves in nonlinear media.
The results of research in the field of femtosecond and terahertz optics of the International Laboratory of "Femtosecond Optics and Femtotechnology" were published in more than 100 scientific articles, including many high-ranking journals.
