Lecturer: PAOLO VILLORESI

Number of ECTS credits allocated: 9


Syllabus
Prerequisites: The Course prerequisites are the concepts of Physics 1 and 2 Courses.
The content of Courses on Electromagnetic Waves and Structure of Matter would be helpful, but it is not mandatory.
Examination methods: During the Course, there are three written tests that cover both theoretical and numerical problems and which allows to split the program and also may lift the requirement of the oral exam if the final evaluation is greater than 23/30.
Alternatively, the Course exam may be passed with a written test and an oral exam covering the entire program.
A brief report is required for each Laboratory activity.
Course unit contents: The Course is essentially divided into the following four parts:

1. Properties of the light quanta, or photons, and the statistics of radiation. Description of classical and coherent light introducing the methods of Quantum Optics and the principles of quantization of the radiation fields. Laboratory on photon statistics and of generation of random numbers on the base of quantum processes using single photon detectors.

2. Generation and propagation of optical beams. Discussion of Gaussian beams properties, high-order modes, orbital angular momentum (OAM) of light. Optical resonators.
Advanced topics: concepts and methods of Adaptive Optics and of Integrated Photonics.
Laboratory on the beam parameter estimation and on diffraction effects. Demonstration of high order modes with OAM. Laboratory on Adaptive Optics.

3. Principles of laser. Generation of stimulated radiation and emission. Quantum electronics and the luminescence. Optical pumping. Optical gain. Saturation of the gain. Radiation noise. Concept of laser action. Different laser realization. Generation of light impulses. Techniques to reach nanosecond, pico, femto and attosecond domains.
Laboratory on Laser sources. Laboratory on ultrafast pulse generation and measurement.

4. Applications. Principles of laser-matter interaction. Focus on laser technologies for photovoltaic.
Introduction to the topics of Quantum Information. Focus on Quantum Communications.

Concept and applications will be constantly associated and discussed along the Course, both in the classroom and in the Labs.
Learning how elaborating of the concepts of light generation and control already have provided new ideas and applications in many areas should provide the stimulus for envisaging new ones.
