Full 3d+1 Modeling Of Tilted-Pulse-Front Setups For Single-Cycle Terahertz Generation: Reply

Bakunov andBodrov [J. Opt. Soc. Am. B38, 2587 (2021)] 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 showhowour 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'. (C) 2021 Optical Society of America.
