Our research at CIO with ultrafast optics includes:
- Pump-Probe experiments for the study of photogeneration of charges in organic semiconductors
- Terahertz spectroscopy techniques for the study of ultrafast charge transport in semiconductors, spin injection in semiconductors, surface and interface non-linear optics. Also the use of THz radiation in other disciplines such as biology, astronomy, study of cultural heritage, medicine and industry
- Fabrication of nanoparticles through femtosecond ablation
- Monitoring laser ablation processes using photoacoustic techniques
- Micromachining and Femtosecond-laser direct writing
- Study of surfaces and interfaces through nonlinear spectroscopy
- Development of nonlinear materials study of their properties (i.e., we have standard experimental set-ups using fs pulses such as Z-scan, two-photon excited fluorescence spectroscopy, Optical Kerr, Wave-Mixing, multiphoton microscopy)
Facilities:
- Regenerative amplifier (delivering 50 fs pulse width, 800 nm, 3.5 mJ/pulse, 1 kHz repetition rate. Libra, Coherent)
- Optical Parametric Amplifier (TOPAS, Light Conversion). Tunable UV-VIS-NIR
- Laser Microfabrication Workstation (uFAB, Newport)
- CCD cameras UV-Vis-NIR and a variety of detection electronics
