V- Transverses modes of laser radiation. Chap. VI- Longitudinal modes of laser radiation. Chap. VII.- General Characteristics of lasers. Example of applications. | ||

Applications Homework will be proposed to familiarize the students with the physics of lasers. Part of this work will be evaluated and taken into account for the final grade. The principle introduced in this course are illustrated in the practical training in experimental physics. | ||

Acquired skills After completion of this course, the student will be able to identify the properties of a particular laser ; he(she) will be able to compare the given parameters with the corresponding theoretical values. He(she) will also be able to modelize a light amplifier, evaluate the expected gain using the intrinsic parameters of the active material. The student will be able to relate the properties of a laser with the accessories introduced inside the cavity. Visits of laser facilities will allow to get a practical representation of laser and laser systems, in particular for applications in measurements and material processing. |
