Research objectives

The laboratory's objective is to design optical elements and control structured laser beams to optimize laser material processing and develop advanced photonics and imaging technologies. It also aims to study the influence of spatial and temporal structure, phase, and polarization of light on the interaction with materials for development of innovative solutions for industrial applications.

Main research areas:

1. Generation and control of structured and non-paraxial light

Formation of Airy, Bessel, Gaussian and vortex beams using silicon diffractive, 3D printed and geometric phase elements; phase, amplitude and polarization engineering of these beams.

2. Applications of THz structured light for imaging

Development of non-paraxial THz beams and their use in single-pixel imaging systems, object edge detection, material characterization and quality analysis of graphene layers.

3. Laser micromachining of transparent media with non-standard beams

Development and optimization of long focal length, linear focus and non-standard cross-sections (circular, elliptical, parabolic) beams for efficient glass cutting, drilling, surface and bulk processing.

4. Development of spatial light modulators, geometric phase and other photonic elements

Design and fabrication of 2D and 3D geometric phase structures, diffractive and spatial spectral elements for ultrashort laser pulse generation and polarization control.

5. Metamaterials, nanoplasmonics and nanoparticle clusters

Metaatom engineering, interaction of structured light with nanostructures and metamaterials, design of new optical functionalities of nanostructures.
