The article focuses on the efficiency of Laser Direct Imaging (LDI) in producing printed circuit boards (PCB) during manufacturing processes. To enable tighter registration between layers, LDI must have continuous wave, ultraviolet source, and a service by large frame argon ion lasers. Furthermore, LDI is important to PCB manufacturers because it helps in solving stability problems by completely eliminating the phototool.

    We demonstrate experimentally the extreme ultraviolet supercontinuum in the plateau of high-order harmonic emission from the argon gas cell driven by a 6.5 fs, 800 nm phase-stabilized laser pulse. The result is interpreted as a selection of single quantum path of the returning electrons due to...
