Editing Fourier-transform spectroscopy (section)

=== Nanoscale spectroscopy with pulsed sources ===
Pulsed sources allow for the utilization of Fourier-transform spectroscopy principles in [[Near-field scanning optical microscope|scanning near-field optical microscopy]] techniques. Particularly in [[nano-FTIR]], where the scattering from a sharp probe-tip is used to perform spectroscopy of samples with nanoscale spatial resolution, a high-power illumination from pulsed infrared lasers makes up for a relatively small [[Scattering cross section|scattering efficiency]] (often < 1%) of the probe.<ref>{{Cite journal|last1=Hegenbarth|first1=R|last2=Steinmann|first2=A|last3=Mastel|first3=S|last4=Amarie|first4=S|last5=Huber|first5=A J|last6=Hillenbrand|first6=R|last7=Sarkisov|first7=S Y|last8=Giessen|first8=H|title=High-power femtosecond mid-IR sources for s-SNOM applications|url=http://stacks.iop.org/2040-8986/16/i=9/a=094003?key=crossref.3eb2b21f107d58830fc324d0ec18d34e|journal=Journal of Optics|year=2014|volume=16|issue=9|page=094003|doi=10.1088/2040-8978/16/9/094003|bibcode=2014JOpt...16i4003H|s2cid=49192831|url-access=subscription}}</ref>
