The scientific project
The objective of this project is to study the generation of coherent electromagnetic radiation and its interaction with matter from the IR to the gamma-ray range. The project is divided into seven research programs :
1. Composite lasers - ISHG
Nd:YAG lasers with Intracavity Second Harmonic Generation (ISHG).
These lasers, which are now available to university laboratories at a reduced price, will be studied theoretically and experimentally. We will exploit their nonreciprocal mode independence to set up a semiclassical cryptography technique. We will also study their peculiar dynamics from the viewpoint of the energy mode distribution.
2. Composite lasers - OPOSA
Optical Parametric Oscillators with Saturable Absorber (OPOSA).
In view of the recent emergence of stable and reliable high power OPO's, we will study the dynamics of an OPO whose driving field can be absorbed by a saturable medium. Particular attention will be devoted to transverse mode coupling due to diffraction.
3. Semiconductor lasers
Semiconductor lasers have a wide range of applications but are known to be unstable devices. Because systematic experiments are difficult, most of our understanding of these instabilities is based on extensive numerical studies. Cascading bifurcations to progressively more complex time dependent regimes is the main mechanism leading to these instabilities. We propose a series of analytical and numerical studies of semiconductor laser bifurcations. Our objective is to compare theoretical and current experimental observations of semiconductor laser bifurcations in the case of a single mode laser subject to either injection or optical feedback.
4. Nuclear quantum optics
We will investigate how the method of quantum interference of atomic levels can be extended to include nuclear transition in order to generate coherent radiation in the gamma-ray range. Analytical derivations of the gain will be crucial to determine if such schemes are feasible.
5. Novel solitons
The ULB group has recently discovered new types of optical solitons. These solitons exhibits interesting features from both fundamental and applied viewpoints. We will study experimentally the propagation of the new solitons in optical fibers. Besides the study of their fundamental properties, our attention will be focused on their potential applications to all-optical data processing and transmission.
6. Optical fiber resonators
We will investigate the dynamics of nonlinear optical fiber resonators. On one hand these devices are subject to complex instabilities which have not yet been systematically studied. On the other hand, these devices exhibit potentially interesting features for applications to all-optical data processing. The main scope of our research activity in this field is to improve the understanding of the various instability mechanisms in fiber resonators and to properly control their basic nonlinear features in view of application to all-optical data processing.
7. Doped fiber devices
Doped fiber lasers, fiber amplifiers and fiber-based data processing devices will be studied numerically and experimentally with a view to investigating their applications to ultrahigh repetition rate photonic transmissions in the different telecommunication wavelength windows. Special attention will be devoted to the design and realization of laser sources for novel vector and compound solitons.
These meetings are opened to all members of the three IAP P4-07 participating labs. The goal of these meetings is to offer to all members of this IAP network the opportunity to learn more about the activities of the other groups, to visit their facilities, but also and maybe essentially, to create personal contacts between the younger scientists, with the hope that they will result in a deeper and more efficient interdisciplinary collaboration between persons who will know each other better than through typed reports and/or e-mail.
The first semi-annual meeting has been organised at the ULB on August, 28, 1997.The best photos of this glorious day
