Dr. Tzortzakis' expertise lies in the field of intense ultrashort laser pulse interaction with matter and he has a broad experience in the following domains:
- Nonlinear interactions of intense femtosecond laser pulses with matter
- Advanced shaping in space and time of light with applications in materials processing
- Nonlinear laser propagation phenomena - filamentation
- Integrated photonic circuits in the bulk of transparent solids
- Quantum and complexity physics with photonic lattices
- Intense tunable THz sources and THz nonlinear Optics
- Tunable THz metamaterials
- Environmental/atmospheric physics
His research team deals with both fundamental science aspects as well as technological applications. The polyvalent nature of their laser facilities allows studies in cross-disciplinary science including physics, chemistry, materials science and bio-medicine.
