This erratum corrects errors in the expressions for and fitted form of and a consequent data point in Fig. 4 of a recent Letter [Opt. Lett. 42, 5018 (2017) [CrossRef] ]. It also supplies data for the reference compound para-nitroaniline (pNA). The correction to improves experimental agreement from 46% to within 21% of independent scissors-corrected density functional theory (DFT) calculations. Central findings from the original Letter remain intact.

Equation (2) on page 5019 in Ref.  contained an extraneous Beer–Lambert correction factor, . Calculation of the orientation-averaged first hyperpolarizability, , for tungsten disulfide (), a transition metal dichalcogenide (TMD), from hyper Rayleigh scattering (HRS) data should instead use1].
The expression for fitted form of in the Fig. 2 caption and in paragraph 5 on page 5019 in Ref.  is missing two terms for TMD to clarify absolute versus relative . Its correct form is1].
The corrected value is . Subsequently, the corrected bulk-like second-order nonlinear susceptibilities, and , are and , respectively, using a mean flake volume of . Figure 1 is the corrected Fig. 4 from Ref. , which summarizes published measured and calculated for monolayer [2,3]. The corrected HRS-measured value differs from the scissors-corrected () DFT value by 21%, rather than 46% as reported in the original Letter . The central findings and conclusions of the original Letter remain intact.
