LASER FUNDAMENTALS

Course objectives

Generals The aim of the course is to provide the student with an understanding of the principles of operation of active optical devices based on the interaction of light with nanoscale systems; it also wants to provide an understanding of the most current laser design and construction techniques (q-dots, photonic crystal laser) and their uses in the field of optoelectronics, quantum information and also in diagnostics that use miniaturized optical sources Specifics • Knowledge and understanding: know analytical methods to understand how lasers work in various fields, as well as know the basic technology of quantum electronics • Ability to apply knowledge and understanding: apply analysis and learning methodologies, through activities also in the laboratory. • Critical and judgmental skills: tests are carried out • Communication skills: knowing how to describe what has been learned in the field of knowledge of technologies operating laser devices. The communication skills are realized by addressing some fundamental topics with the request for active participation in the solution of problems, based on the knowledge acquired from previous lessons or from courses already passed. • Ability to continue the study independently throughout life: ability to continue subsequent studies concerning advanced themes of photonics and quantum electronics, based on the acquired analysis and project methodologies.
