Abstract
Bakunov and Bodrov [ J. Opt. Soc. Am. B 38, 2587 (2021)JOBPDE 0740-3224 10.1364/JOSAB.404387 ] claim that equations used in our work do not correspond to the conventional configuration for tilted-pulse-front terahertz generation and that angular dispersion along the z ′ axis was not included. Here, we show how our numerical model was set up and prove that it does correctly capture the physics of the conventional tilted-pulse-front configuration, where the image of the grating is aligned with the tilted pulse front of the pump pulse. We show that angular dispersion in both x ′ and z ′ dimensions is included via conservation of momentum instead of a Taylor expansion along z ′ .
