Research experience and interest: 
  • Trace analysis of solids using laser ablation combined with Resonance Ionization Spectroscopy (LARIS) and RI Mass Spectrometry
  • Elemental microanalysis of solid samples with Laser Ionization Mass Specrometry (LIMS)
  • Application of LARIS and LIMS to the measurement of surface impurity distributions on deposition probes exposed to tokamak or stellarator discharges
  • Study of laser-pulse-generated atomic beams (blow-off) by resonance fluorescence, ionization and LIMS
  • Detection of imprisonment of resonant radiation in laser blow-off beams
  • Development of ultrashort-pulsed laser ablation and ionization mass spectrometry
  • Detection of ion content in prepulse plasmas with ultrashort-pulsed LIMS
  • Elemental analysis of microscopic geological samples of terrestrial and extraterrestrial origin
  • Experimental laser ablation investigations into the high-pressure induced material transformations of solid geological targets, relevant to hypervelocity impact processes in earth sciences
  • Cooling and trapping of Rb atoms in a Magneto-Optical Trap (MOT)
  • Coherent momentum transfer to trapped Rb atoms by Adiabatic Rapid Passage (ARP) using frequency-modulated (chirped) laser pulses
  • Electrically Induced Transparency in cooled Rb atoms using chirped laser pulses
