Welcome to the UNIS group website. Here you will find our research activities, publications, highlights, information about our team and available open positions.

In our group we are working in the field of intense ultrashort laser pulse interaction with matter. Our activities are grouped in 3 directions.

We study the nonlinear propagation of intense ultrashort laser pulses in transparent media and related filamentation processes. We develop experimental tools to monitor the interaction of the strong laser fields with the matter and also ways to control the nonlinear propagation through the use of "exotic" wavepackets or photonic lattices.

In the second direction we develop novel strong field THz sources. We are investigating mainly filamentation based approaches and explore novel ways for increasing the source peak power. We are proposing ways of taming the source properties through filamentation tailoring methods or using novel artificial materials like metamaterials and eutectics. With the available THz intensities we explore the new era of nonlinear THz optics.

Finally, in the third direction we use photonic lattices for a number of applications. From the control of the nonlinear propagation, to the study of complexity physics and quantum information and quantum analogs.

In our research we are dealing with both fundamental science aspects as well as technological applications. The polyvalent nature of our facility allows studies in cross-disciplinary science including physics, chemistry, materials science and bio-medicine.

Our group profits from financing coming from National and European Union sources.

Our facility is open to collaborations with European researchers through the Laserlab-Europe network. For more information you may contact us at unis@iesl.forth.gr

Our group lunched in 2009 and operates since then Filamentation.org, a unique information resource on the field of intense short pulse nonlinear laser propagation phenomena.
