The use of a ceramic substrate resulted in the fabrication of nozzles with high circularity and low roughness, which should generate high-quality gas targets for accelerating electrons with ultrashort laser pulses.openAccesslaserswakefield acceleratorsnozzlesmeasuring methodsDevelopment of dielectric de Laval nozzles for laser electron acceleration by ultrashort pulses micromachiningTexto completo de evento10.1109/SBFOTONIOPC50774.2021.94619280000-0001-7762-89610000-0003-0092-9357https://orcid.org/0000-0001-7762-8961https://orcid.org/0000-0003-0092-9357
