Research Areas

The conversion of solar radiation into laser radiation by solar pumping is of increasing importance because free broadband sunlight can be converted into amazing laser light, which is a source of narrowband, collimated radiations with extremely high brightness and intensity. Our solar laser laboratory at New University of Lisbon was established a decade ago, embarking on a challenging journey to significantly improve both solar-to-laser conversion efficiency and the output beam quality of solar-pumped lasers. Thanks to a huge amount of painstaking research efforts, we have attained some international recognitions and highlights.
