Learning Objectives
Knowledge and comprehnsion of main processes of non linear optics, light matter interaction matter particularly for laser, coherent processes and propagation of light and means for its optical control . Links to other topic of the Laurea Magistrale. Capacity in apply knoledgedge a study with autonomy. The course , in the limit of a University course, is aimed to stimulate the communicative skills and the capability of understunding. These objectives will be evaluted during the examination.
Prerequisites
Lectromagnetism. Basic quantum mechanics.
Teaching Methods
Lessons and exercises
Further information
Learning materials present in moodle
Type of Assessment
Only oral examination of approximately 50 minutes. The examination is divided in two parts. In the first the student presents a free part of the course and answer at the questions of the commission. In the second part the commision will ask on a different topics with relative questions.
Knoledge of the topics presented anbd answered, both from a theoretical and experimental/relizative point of view, clariity of exposition and autonomy of rasoning will be the main criteria of judgement.
