AB  - The strong-field process of high-harmonic generation is the foundation for generating isolated attosecond pulses1, which are the fastest controllable events ever induced. This coherent extreme-ultraviolet radiation has become an indispensable tool for resolving ultrafast motion in atoms and molecules2, 3. Despite numerous spectacular developments in the new field of attoscience2, 3, 4, the low data-acquisition rates imposed by low-repetition-rate (maximum of 3 kHz) laser systems5 hamper the advancement of these sophisticated experiments. Consequently, the availability of high-repetition-rate sources will overcome a major obstacle in this young field. Here, we present the first megahertz-level source of extreme-ultraviolet continua with evidence of isolated attosecond pulses using a fibre laser-pumped optical parametric amplifier6 for high-harmonic generation at 0.6 MHz. This 200-fold increase in repetition rate will enable and promote a vast variety of new applications, such as attosecond-resolution coincidence and photoelectron spectroscopy7, or even video-rate acquisition for spatially resolved pump–probe measurements.
