Lasers physics
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.
5 credits
22.5 h + 7.5 h
Having followed LPHYS2143 is an asset
Main themes
Reminder on light-matter interaction, homogeneous and inhomogeneous broadening, gas lasers, dye lasers, solid state lasers, pulsed lasers and applications.

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


a.     Contribution of the teaching unit to the learning outcomes of the programme (PHYS2M and LPHYS2M1)


AA 1.3, AA1.4, AA 1.6, AA 2.1, AA 2.2, AA 5.3, AA 6.3, AA7.1, AA 7.2, AA7.5, AA7.6, AA 8.1


b.    Specific learning outcomes of the teaching unit


At the end of this teaching unit, the student will be able to:


1.   recognize the most used lasers and their basic principles ;

2.   have in mind the orders of magnitude of important properties of several important lasers ;

3.   conceive a basic laser layout and being able to spot strength and bottleneck of this set-up ;

4.   explain few applications of lasers in fundamental and applied physics ;

5.   conceive different set-up to test the basic properties of a laser ;

6.   build an interferometer.


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”.
Reminder on light-matter interaction
Homogeneous and inhomogeneous broadening
Gas lasers
Dye lasers
Solid state lasers
UV, XUV lasers
Fiber lasers
Frequency control of a laser
Applications : spectroscopic and distance measurements
Introduction to mode-locked lasers
Teaching methods
Lectures, laboratories and experimental demonstrations, applied projects
Evaluation methods
The student will be evaluated based on a written report concerning an experimental or theoretical project on lasers. The evaluation will also be based on the defense of this project and an oral examination.
