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.
Target skills and knowledge: The light and its properties are at the core of established technologies such as Telecommunication Photonics or Laser Processes in Medicine and Industry, as they are crucial for emerging sectors such as the Photovoltaic Energy Generation or Quantum Communications.
It is therefore strategic to learn and to practice a language to understand how to generate and use the light, which principles operate the laser and the thermal radiation sources, including the Sun and the conventional sources, and how the optical beams propagate and transform and it is used in many areas.
The Quantum Optics and Laser Course aims to bring the students closer to the concepts on which lasers work, to the characteristics of the different types of light, classical, coherent, quantum, the interaction between radiation and matter, how the principles of ' Laser action can be realized in very different ways and how to exploit them.
The Course also provides an approach to the methods of Quantum Optics for understanding the origin of radiative phenomena, and an approach to quantum technologies, currently of great interest and development.
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.
Assessment criteria: The evaluation is based on the addressing of several aspects:
1) the knowledge of the key concepts of the program,
2) the ability to solve numerical problems related to selected parts of the Course and which represent significant cases and applications for understanding.
3) the elaboration of significant observations made in the Laboratory in the form of a brief reports.
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.
Planned learning activities and teaching methods: The didactic aims of the Course are to activate different aspects:
1) to develop autonomous learning processes in the field of generation and application of light and laser sources. This is not only based on the standard program, but also on Focus on current issues of particular interest and with examples of successful cases of technology transfer and spin-off.
2) to provide a customizable training offer, in particular by providing the student with predominantly theoretical and experimental approaches as a starting point for further study.
3) to promote and consolidate the interest and motivation of students towards the photonics sector, lasers and modern information technology technologies, which are crucial to societal progress.

Python modules are used as didactical tools for Quantum Optics, providing the rapid acquaintance with both symbolic descriptions, numerical examples and graphical animations.
Additional notes about suggested reading: The Course provides auxiliary study materials to the textbook and addresses the contents and stimulates interest and understanding.
These include:
1) scientific publication and technical descriptions of interest for specific aspects, such as latest discoveries or "classical" items in an industry.
2) calculation programs for the modeling of equations and processes dealt with in the course.
