  We recently demonstrated a widely tunable THz molecular laser and reported
mathematical formulas and a table for comparing how various molecules would
perform as such lasers (Chevalier et al., Science, 15 November 2019, p.
856-860). Here we correct the value of a single parameter used to calculate the
table (see Erratum for Chevalier et al.), thereby eliminating the concerns
raised by Lampin and Barbieri (Lampin et al., arXiv:2004.04422). We also show
that our simplified model for the output THz power is a better approximation
than the alternative one proposed in the technical comment.
