*Note from June 29, 2020*

Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

1 |
a. Contribution of the teaching unit to the learning outcomes of the programme (PHYS2M and PHYS2M1)AA 1.1, AA 1.2, AA 1.3, AA 1.4, AA 1.5, AA 1.6, AA 2.1, AA 2.2 b. Specific learning outcomes of the teaching unit At the end of this teaching unit, the student will be able to: 1. understand basic principles of optics used for example in beamsplitters, multidielectric mirrors or filters, gratings, interferometers, optical devices ; 2. use Fourier optics to solve problems of diffraction ; 3. measure temporal of spatial coherence of light sources ; 4. calculate the propagation of Gaussian laser beams ; 5. recognize the necessary conditions to build a continuous-wave laser |

Content

The teaching unit is structured as follows:

1. General optics : decomposition in plane waves, polarization, linear interaction with matter, refraction, Fresnel laws, geometrical optics, imaging systems, Jones matrices, interferences, diffraction, temporal and spatial coherence, Fourier optics;

2. Lasers physics and basic properties of lasers : amplifying medium, laser cavity, Q-Switch, propagation of Gaussian beams.
