Laser Physics Laboratory 1
A.Y. 2019/2020
Learning objectives
The aim of the course is to give an introduction to the basic theory of laser systems and to provide the appropriate knowledge to design, build and test a laser working in three different regimes: continuous, Q-switched and mode-locked.
Expected learning outcomes
At the end of the laboratory course the student will have a detailed knowledge of more optical techniques, in detail:
1) alignment of an optical cavity and a laser
2) measurement of relaxation oscillations of different lasers
3) measurement of frequency differences between the modes of a laser
4) realization of a single mode laser
5) realization of a pulsed laser in Q-switch regime
6) measurement of the temporal length of the pulses of a mode-locked laser
