Atomically thin materials like graphene and semiconducting transition metal dichalcogenides (TMDCs) have drawn broad interest in recent years, provoking investigation into multiple properties. In this work, we used the Raman optothermal technique to measure the thermal transport properties of a popular TMDC material WSe

, in the single-atomic layer (1L) form in both suspended and supported form. We implemented more direct measurements of the 1L WSe

's absorption coefficient from the measurements. In addition, by comparing the response of 1L WSe

using several kinds of laser spot sizes, we are able to obtain the lateral thermal conductivity of 1L WSe

and the interfacial thermal conductance to the substrate. For 1L WSe

, the room-temperature thermal conductivity is 36 ± 12 W/(m·K) in supported form and 43 ± 13 W/(m·K) in suspended form. Significantly, the interfacial thermal conductance of 1L WSe

is determined to be 2.89 ± 0.45 W/(m
