Coherent Optics Laboratory

Head of laboratory dr. Sergejus Orlovas
phone +370 5 2665792

Laboratory was established by the Centre together with UAB „Altechna R&D” in 2016. Laboratory is mainly designing optical focal spots and lines with polarization control for applications of laser microprocessing of materials. Microprocessing of materials is not the only area of scientific interests. We are interested also in

  • Metamaterials and nanoplazmonics. Clusters of nanoparticles, design of metaatoms,
  • Precise nanointerferometric measurement of electromagnetic fields using nanostructures (spheres, knive-edges etc),
  • Pecularities of vector beam propagation with topological charges (vortices, vector singularities)
  • Charged particles acceleration using vector electromagnetic beams,
  • Nonlinear interactions during parametric processes in quadratic and cubic materials
Coherent Optics Laboratory is open for contractial R&D. For more information contact dr. S. Orlov.

PHABLABS 4.0, PHotonics enhanced fAB LABS supporting the next revolution in digitalization
12.2016 - 12.2019

Combining the World of Photonics and Fab Labs. The concept of PHABLABS 4.0 is based on combining the World of Photonics with the growing creative ecosystem of existing Fab Labs. Joining forces of top experts from 13 European photonics institutes and STEM-oriented organizations with Fab Lab stakeholders, PHABLABS 4.0 will deliver 33 Photonics Workshops, 11 Photonics Challengers and Photonics Toolkits tailored for three different target groups.
