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.
Target skills and knowledge: The light, its language and its properties, the quantum nature of the radiation, the sources of natural and coherent, laser, light as well modern applications of these concepts in areas ranging from advanced communications to industrial processing are the topics of this Course.

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 the 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 in the area of Quantum Communications.

In its various articulations the Course has the following knowledge and skills targets:
1. Critically learn and interpret the main concepts related to the generation, propagation and use of light.
2. To know the main mathematical models that describe the processes of generation and propagation.
3. Know how to recognize the type of interaction of light with different materials.
4. Know the main areas of application of light, especially in an interdisciplinary context.
5. To be able to synthesize the analysis of optical or laser beam measurements, as seen in the Laboratory, in a professional report.
Examination methods: During the course there are four homework and some laboratory reports. The last homework will be the elaboration of an assigned theme, the other homework cover both theoretical aspects and numerical problems. The reports are brief reports on the measures taken in the Laboratory.
As an alternative, the exam of the Course is passed with a written test and an oral exam on the whole program.
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:

Properties of the light quanta, or photons, and the statistics of radiation. Description of classical and coherent light introducing the methods of Quantum Optics. Introductory concepts of quantization of the atoms and of radiation fields. Laboratory on photon statistics and of generation of random numbers on the base of quantum processes using single photon detectors.
2. 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 pulses. Techniques to reach nanosecond, pico, femto and attosecond domains.
Laboratory on Laser sources, on pulse generation and measurement.
3. Generation and propagation of optical beams. Discussion of Gaussian beams properties, high-order modes, orbital angular momentum (OAM) of light. Optical resonators.

4. Applications: Principles of laser-matter interaction and examples in industrial and medical processes. Introduction to Quantum Information and Quantum Communications using single and entangled photons, and the main applications.

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.

Matlab and Python codes 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.
