Module : | Laser and non-linear optics |
Author(s) : | François BALEMBOIS & Sébastien FORGET (contributeur) - Institut d'Optique – Graduate School |
Date of creation : | non renseignée |
Resume: | After a historic, we get onto the principles of interactions between light and matter and the conditions that lead to light amplification. Then we treat the oscillator laser which is the association of a resonant cavity and a light amplifier area. Finally, we describe the devices behind the word « laser » : oscillators and amplifiers, solid lasers, liquid (colouring) or gaseous. |

Module : | Laser and non-linear optics |
Author(s) : | François BALEMBOIS & Sébastien FORGET (contributeur) - Institut d'Optique – Graduate School |
Date of creation : | 2008 |
Resume: | Lasers are more and more performant and diverse. Continuous and pulsed laser sources are now available, with wavelengths ranging from the visible spectrum to the infrared and UV. They also deliver powers ranging to the kilowatt. As a consequence, it is necessary for any user to take enormous precautions concerning laser safety, in order to prevent any injury.The aim of this course is to educate the potential users of laser sources about their risks and the adequate behaviour while manipulating them. |

Module : | Laser and non-linear optics |
Author(s) : | Sébastien FORGET - Laboratoire de Physique des Lasers - Université Paris Nord/13 |
Date of creation : | non renseignée |
Resume: | The aim of this module is to describe how the spatial and spectral structure of laser beams are impacted by the optical resonator properties. We also study the stability of laser resonators and the propagation of Gaussian beam through optical systems. |
