By virtue of their low mass and stiffness, atomically thin mechanical resonators are attractive candidates for use in optomechanics. Graphene, in particular, is an ideal material to investigate as it possesses excellent electrical and mechanical properties as well as a strong interaction with light over the entire visible range. Here, we demonstrate photothermal back-action in a graphene mechanical resonator comprising one end of a Fabry-Perot cavity. As a demonstration of the utility of this effect, we show that a continuous wave laser can be used to cool a graphene vibrational mode or to power a graphene-based tunable-frequency oscillator. In addition to enabling studies of fundamental physics, the remarkable sensitivity of graphene optomechanical resonators and their ability to operate over a broad range of wavelengths and mechanical frequencies makes them attractive for applications.
