In this paper we investigate the absorption and radiation of nonminimally coupled scalar field from the charged BTZ black hole. We find the analytical expressions for the reflection coefficient, the absorption cross section and the decay rate in strong coupling case. We find that the reflection coefficient is directly governed by Hawking temperature $$T_{H}$$TH, scalar wave frequency $$\omega $$ω, Bekenstein–Hawking entropy $$S_{BH}$$SBH, angular momentum m and coupling constant $$\xi $$ξ.
