In the article “;High-flux soft x-ray harmonic generation from ionization-shaped few-cycle laser pulses,” changes were made to sentences throughout the text to correct inaccuracies that were present from confusing wording introduced following final proof correction. In the last sentence of the Abstract, wording was corrected from “to fields that drive even longer wavelengths” to “to even longer-wavelength driving fields”. In the second paragraph of the Introduction, a sentence describing HHG was revised to correct ambiguity and now reads, “HHG can then be said to be in the overdriven regime when plasma lensing causes the beam to be rapidly reshaped.” In the first paragraph of the Results section, text incorrectly referencing Fig. 1B stated, “The excellent spatiotemporal quality of the driving pulse suppresses beam breakup”. The text was corrected to read, “Beam breakup is suppressed by the excellent spatiotemporal quality of the driving pulse, evidenced by the symmetric and smooth spatiotemporal profile (Fig. 1B) measured using SEA-F-SPIDER (24).” In paragraph 6 of the results section, a poorly worded sentence was corrected to read “Because of the strong spatiotemporal reshaping, it is likely impossible to achieve high-flux harmonic generation without a pristine input pulse as in our case, which simultaneously ensures a good spatial profile for the harmonics.” The HTML and PDF versions of the paper have been corrected.
