Optics and lasers
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.

Lauzin Clément;
LPHYS1221 for the students enrolled in the Bachelor in physics who wish to follow this teaching unit within the additional module in physics.
Main themes
Basic teaching unit, giving a description of all aspects of general optics and an introduction to laser physics.

At the end of this learning unit, the student is able to :

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

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.
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.
Teaching methods
Ex-cathedra and 5 experimental laboratories.
Evaluation methods
Written : problems to solve and questions about the theory
