We construct Adams operations ψk on the cohomology theory Tmf of dualisable topological modular forms after inverting k; the first such multiplicative stable operations on this cohomology theory. These Adams operations are then calculated on the homotopy groups of Tmf using a combination of descent spectral sequences and Anderson duality. Applications of these operations are then given, including constructions of connective height 2 analogues of Adams summands and image-of-J spectra.
