Winter College on Optics to focus on frequency combs

The 2016 Winter College on Optics at the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy, will be held 15-26 February and focus on optical frequency combs.

ICTP logoThe emphasis for this year’s event responds to the need to provide physicists with a comprehensive overview on the properties of frequency combs, their synthesis, and their main applications, specifically molecular spectroscopy and trace gas sensing.

Frequency combs have revolutionized the field of optical-frequency metrology and paved the way to a new generation of atomic clocks based on ultra-narrow optical transitions. Their fine, discrete, stable, reproducible, and controllable spectral structure, readily referable to the primary microwave standard, also make combs ideal tools for high-resolution molecular spectroscopy and sensing of multiple trace gases.

Instruction will include multispecies gas sensing to high-precision interrogation of atomic and molecular targets. The main topics will be:

  • Optical frequency combs: the history of a Nobel prize
  • Introduction to stable phase sources, optical clocks, and coherent frequency transfer
  • Optical frequency combs across the spectrum
  • Molecular spectroscopy and trace gas sensing
  • Linking old and new: High-precision, comb-assisted spectroscopy
  • Interaction of the femtosecond pulse train with an atomic or molecular sample - direct frequency comb spectroscopy
  • Frequency combs for broadband spectroscopy and trace gas detection
  • Testing the limits (tests of fundamental physics, attosecond timing, etc.)

Among the lecturers are directors for the 2016 Winter College: Kristan Corwin of Kansas State University (USA), Marco Marangoni from Politecnico di Milano (Italy), and Piotr Maslowski of Nicolaus Copernicus University (Poland).

SPIE is a longtime cosponsor of the Winter College on Optics. Other cosponsors are the International Commission for Optics (ICO); the Optical Society (OSA), the European Optical Society (EOS), Società Italiana di Ottica e Fotonica (SIOF), and the International Society on Optics Within Life Sciences (OWLS).

An ICTP Preparatory School will be organized the week before the College (8-12 February 2016) for a limited number of selected participants. The Preparatory School will provide background tutorials and exercises designed to help the participants in following the College lectures.
