Obiettivi dell'insegnamento

To give examples of application of ultrashort light pulses to the study of dynamical processes in physics, chemistry and biology.

To discuss real-world applications of ultrashort pulses to microscopy and material processing.

The acquired knowledge will enable the student to work in advanced research laboratories as well as in high tech companies developing laser sources or using them for applications in micromachining, telecommunications, sensing or biomedicine.


Risultati di apprendimento attesi

At the end of the course the student will acquire knowledge and understanding of the underlying physics and the technical working principles of ultrashort pulse laser systems (DD1).

The student will be able to apply this knowledge and understanding to different scientific and industrial systems using ultrashort pulse lasers  (DD2).

The student will be able to make judgements on the design of such systems for applications to spectroscopy, imaging or material processing (DD3).

The student will acquire learning skills that will enable her/him to read andvanced, graduate-level textbooks on nonlinear optics and photonics as well as papers on peer-reviewed scientific journals (DD5).


Argomenti trattati

Ultrafast spectroscopy

  • introduction to ultrafast spectroscopy techniques;
  • degenerate, two-colour and broadband pump-probe;
  • density matrix formalism for the description of light-matter interaction;
  • four-wave mixing and photon echo, 2D spectroscopy;
  • ultrafast processes in metals and semiconductors;
  • applications to femtochemistry and femtobiology.

 

Real-world applications of ultrashort pulses

  • Nonlinear microscopy techniques: second-harmonic and third-harmonic generation microscopy
  • coherent Raman microscopy: Coherent Anti-Stokes Raman Scattering (CARS), Stimulated Raman Scattering (SRS)
  • Material processing with ultrashort laser pulses: high precision cutting and drilling
  • Micro- and nano-fabrication with ultrashort laser pulses: two-photon polymerization.
  • Large-scale laser facilities (free electron lasers…)

Prerequisiti

The course requires basic knowledge of the foundations of classical electromagnetism, quantum electronics (light-matter interaction, principles of lasers) and quantum mechanics.

A good understanding of the topics handled in the course of Photonics is an important but not necessary prerequisite. 

It is preferable to take the "PHYSICS OF ULTRAFAST PROCESSES" course before this one, even if it is not compulsory.


Modalità di valutazione

The evaluation will consist of a written exam (two hours duration) with questions and/or problems covering the topics of the lectures.

The exam will test the depth of understanding by the student of the handled topics, the developed critical skills and the capabilities to effectively organize the presented material, using a proper lexicon and efficiency and linearity of the discussion.
