The Radiation Physics Laboratory in the Mathematics and Physics Department has more than 25 years of experience in the field of laser-matter interaction and thin films deposition via laser ablation. The deposition of thin films with adequate morphology and a crystalline structure is a key point in the development of many research fields. The versatility of pulsed laser deposition via laser ablation lies in the possibility of obtaining films very adherent to the substrates, even at room temperature, and a high predictable growth rate, which can be precisely controlled through a priori studies of the experimental parameters. Our current research is mainly focused on the production of photocathodes based on metallic thin film prepared by pulsed laser deposition and tested in a home-made photodiode cell.
