The need for continuous advancement of ultrafast laser technology obviously poses technological and scientific challenges to laser developers. At the same time the upgraded laser specifications also requires new solutions from scientist aiming to work with them. The usage of cutting-edge lasers to drive high-harmonic generation beamlines needs careful considerations to obtain efficient, high-flux attosecond sources. The design of appropriate gas targets for phase-matched generation of extreme ultraviolet radiation, or proper shaping of the driving pulsed laser beam are key factors for reaching these goals. In my talk I will give a brief overview of a few aspects of this broad topic, including questions one might face when designing an attosecond beamline after buying a brand-new laser. These guidelines will be supplemented by a few examples from ELI ALPS – the first ever user facility in attosecond science – and some laboratories around the world.
