Nature 522, 462–464 (2015); doi:10.1038/nature14517 After reading ref. 1 we became aware of a mistake in this Letter. The last sentence of the legend of Fig. 1b should have read: “The delay of the second harmonic is defined in cycles of the second harmonic.”. As a result, the even harmonics modulatetwice per cycle of the second harmonic in Figs 1b, 3 and Extended Data Fig.
