Minicourse on
Spatial Nonlinear Optics
27-28 May 1998
Optics and Fluid Dynamics Department
Risø National Laboratory
Nonlinear optics provides a convenient medium for studying a number
of universal nonlinear phenomena. Examples include propagation and
interaction of solitons, optical vortex dynamics, pattern formation,
modulational instabilities, and parametric subharmonic instabilities.
Spatial nonlinear optics is an active research topic both for basic
scientists, and for engineers seeking to solve information technology
problems using nonlinear techniques.
This minicourse will present selected topics from current research in
nonlinear spatial phenomena in optics. A combination of theoretical
lectures and laboratory demonstrations will provide graduate
students the opportunity of hands-on experience.
