Laser Applications

Laser Applications

(8th semester - 3 hours teaching weekly)

Teaching jointly with Dr. M. Fakis.


Course Outline:

  • The laser as light source: properties of laser radiations, principles of laser operation. Laser sources for Spectroscopy.
  • Scattering of light: Rayleigh, Mie, Raman, Brillouin.
  • Instrumentation for Spectroscopy: diffraction and optical gratings, lenses, mirrors, filters, beam-splitters, polarizers, monochromators-spectrographs, Light Detectors (photomultipliers, photodiodes, diode arrays, CCD, ICCD, semiconductor based detectors for IR radiations, streak camera).
  • Devices and Instrumentation for measuring low level electrical signals: Lock–in amplifiers, Boxcar integrators.
  • Laser Spectroscopy: Laser Induced Fluorescence (LIF), Multi-photon Ionization Spectroscopy (MPI), Raman Spectroscopy, Infrared Spectroscopy (IR).
  • Laser Induced Plasma Spectroscopy.
  • Laser cooling. Bose–Einstein condensation.
  • Introduction to Nonlinear Optics: the nonlinear optical susceptibility, wave equation description of nonlinear optical interactions, nonlinear absorption and refraction, second and third harmonic generation, nonlinear optical materials, the “all–optical” processes.
  • Optical Trapping and applications in Biology and Medicine.
  • Bio-photonics: basics of laser tissue interactions, Photodynamic Therapies.
  • Bio-nano-photonics: applications of nanoparticles (quantum dots, metallic nanoparticles) in medical imaging and diagnostics.
