Some Examples of Lasers in Research

  • Ultrafast lasers are used to probe properties of chemical bonds in molecules and changes that take place in molecular and electronic structure during chemical reactions 8, a, b.
  • Lasers are employed in chemical sensing c, d, imaging c, d and in experimental strategies aimed at single molecule detection d, e, f.
  • Laser beams are used as molecular tweezers in optical trapping g experiments.
  • Lasers are used as sensitive probes of surfaces and interfaces e, h.
