Local welding of glass with ultrashort laser pulses

The scientific topics are:

  • Micro-and nanostructuring with ultrashort laser pulses
  • 3D structures inside glasses and crystals
  • Linear and nonlinear optics in discrete systems
  • Fiber Bragg Gratings
  • Ultrafast laser applications in ophthalmology
  • Ultra-short pulse laser technology
  • THz generation

Some outstanding results are: direct visualization of the hole drilling of opaque materials with ultrashort laser pulses • realization of high-strength bonds in glass by local laser welding with ultrashort pulses • realization of Fiber Bragg gratings in multimode fibers with ultrashort laser pulses • realization of volume Bragg gratings in fused silica with ultrashort laser pulses • investigation of discrete optical effects in fs written two-dimensional waveguide array • experimental simulation of the relativistic oscillatory motion in fs written waveguide array • analysis of photon correlations in two-dimensional waveguide arrays • optimization of cutting geometry in eye surgery with ultrashort laser pulses.
