Photophysics and Thin Films

Members of the Academic Staff

In our laboratory we study the light-matter interaction, the processes that originate and applications of this interaction, such as, for example, the growth of thin films by laser ablation.

As light sources, we basically use pulsed lasers of duration ns and we study matter in solid, liquid, gaseous and plasma states. We have developed optical, acoustic, mechanical, thermal and electrical techniques to study the interaction of these short pulses. The applications are varied, from analytical techniques, to nanostructuring surfaces or making chemical sensors.

We are a group of researchers with different abilities and we have several funded projects, where we have the possibility of obtaining scholarships to do thesis.

Although the doors of the laboratory are closed, come, knock that we open you and we will tell you about the different projects and perhaps some will interest you.

We are mostly experimental, but we collaborate with theoretical groups and in these times of pandemic we are increasingly giving more attention to modeling the phenomena of the interaction of light with matter.

¡¡¡¡Come we need you!!!! You will be the researchers of the future.

We have 4 optical tables, where Nd: YAG lasers with their harmonics (1064, 532, 355 and 266 nm), excimer lasers at 248 nm, a parametric oscillator (pulsed laser tunable from 200 to 2500nm) are located. We have vacuum chambers to make thin films by laser ablation and by sputtering and all the instrumentation to characterize the light pulses. We diagnose the light-matter interaction using various optical, acoustic, and electrical techniques, such as emission spectroscopy, with temporal resolution, photoacoustics and Langmuir probes, for example.

We have equipment to carry out theses of any level and postdoctoral stays, we just need hands.
