Gaspar Orriols

Gaspar Orriols has done experimental and theoretical research on Laser Spectroscopy and Quantum Optics, Nonlinear Optics and Nonlinear Dynamics since 1975. His main findings include (the participation in) the discovering and explanation of the energy pooling phenomenon in collisions between excited atoms and of the coherent population trapping, which has now become a classical issue in quantum optics. He built up a research group at the UAB devoted to Nonlinear Systems with findings on optical bistability (cavity optimization by separating functions in thermooptical bistability), nonlinear dynamics (amplitude death effect and full instability behavior), nonlinear optics (second harmonic generation in poled glasses) and multilayer optics (patent on a technique for best visualization of blood vessels). Recent research goals include potential connections of the complex oscillatory dynamics of the full instability behavior with complex problems like fluid turbulence and brain dynamics, as well as with the evolution of systems at both macro and microscopic scales.
