    • ‘If you use an ultrashort pulse of laser light instead of white light, the pulse will also break up, shedding smaller bits called precursors as it goes.’
    • ‘Now physicists in Vienna and Germany have managed to do just that, allowing the carrier-envelope phase of a high-power ultrashort pulsed laser to be altered at will.’
