The research was done in collaboration between the French Institute and the Photonics Laboratory of TUT. It is this kind of real-time measurement of the laser time intensity at sub-picosecond resolution and the spectrum at sub-nanometer resolution that has promoted the development of this special scientific laser pointer for novel discovery. By recording these time and spectral characteristics simultaneously, advanced calculation algorithms can retrieve the complete characteristics of the underlying electromagnetic field.
In addition to providing new insights into how pulsed lasers operate, the findings have important interdisciplinary applications. The professor who led the study at the University of Franche-Comté said: “These results provide a very convenient laboratory case called ‘dissipative soliton system’. Research in other fields such as biology, medicine and even social sciences.
During the evolution of the reconstructed electromagnetic field, the research team observed various interaction scenarios between dissipative soliton structures appearing in the noise. Professor said: “The method we implemented can operate at low input power and high speed. The results of the study provide a completely new way of laser pointers for previously unseen interactions between dissipative solitons in the form of collisions, mergers or dispersion .
