PhD in Physics Engineering (2017, FCT-NOVA)
During my research career in the CEFITEC Laser Technology Group, within the scope of the doctoral scholarship SFRH/BD/90410/2012, I contributed significantly to the main advances in the performance of solar-pumped lasers, some of which were highlighted internationally. . I also actively participated in six projects funded by SFERA (Solar Facilities for European Research Area) I-II Horizon 2020. I am currently a junior researcher in the area of solar laser at FCT-NOVA, under contract CEECIND/03081/2017. Since then, I have actively participated in three more projects funded by SFERA-III and I am, at the moment, as main researcher of an exploratory project EXPL/FIS-OTI/0332/2021, which consists of developing a prototype for the simultaneous pumping of several laser crystals with a broader absorption spectrum in the visible region, using concentrated solar energy. This project will allow the simultaneous emission of several solar laser beams with improved performance and thermal efficiency, which could pave the way for the future application of this renewable technology.
