The generation of structured laser pulses with increasingly exotic space-temporal profiles is closely linked to the development of characterization techniques, making this interdisciplinary research line crucial in LUMES. Several researchers in the unit are international references in the development of ultrashort pulse characterization techniques. In addition to designing new characterization techniques in the visible and infrared spectra (such as the STARFISH technique), they are pioneers in the characterization of structured pulses in the extreme ultraviolet. In this regard, the article [Optica 4, 520 (2017), >80 citations] is an international reference for the generation and characterization of vectorial X-ray pulses. This work was developed in collaboration among several unit members, where numerical calculations were performed on the USAL cluster, and experiments were conducted at the Center for Pulsed Lasers (CLPU). Therefore, this is an example of collaboration between researchers and associated infrastructures, now integrated within the LUMES unit.
