Research group activities

Laser Matter Interaction Group is engaged in the following activities:

  • The development of novel methods for microfabrication of transparentand metallic materials with Lithuanian-made femtosecondlaser systems; 
  • Volumetric modification of transparent materials via femtosecondlaser pulses; waveguide and other photonic device integration inglasses;
  • The application of Laser induced breakdown spectroscopy (LIBS) for monitoring of femtosecond laser micromachining;
  • Development and optimization of Synchronously PumpedOptical Parametric Oscillators (SPOPO) by femtosecond pulses;
  • Research on supercontinuum generation in photonic crystalfibers; nonlinear optics, vortex beam generation;
  • Research on ultrafast coherent spectroscopy in terahertz range.



Long term or project based collaboration with academia and industrytowards development of ultrafast laser machining and advancednonlinear applications. Feasibility studies or small scale batch production are available viaopen access facility “NAGLIS”.
