Publisher's Note: "High brightness betatron x-ray source driven by chirped laser pulses" [Phys. Plasmas 31, 103105 (2024)].

This article focuses on corrections made to a previously published scientific paper involving chirped laser pulses and pulse front tilt (PFT). The corrections include changing the term "bubbles" to "bubble" in the abstract, deleting an extraneous article before "chirped laser pulses," adding a sentence confirming the presence of PFT in the laser pulse on page 3, and removing an unnecessary article before "positively chirped laser" in the conclusions. These amendments were applied to all online versions by 10 October 2024, ensuring consistency with the printed journal version.
