Superconducting RF (SRF) Free Electron Lasers (FELs) worldwide are reviewed. Two examples of high performance SRF FELs are discussed in detail: the TTF-FEL at DESY, which recently demonstrated lasing at the wavelength of 109 nm and the Jefferson Lab IR FEL, which recently lased at the average power of 2.13kW. Inspired by the success of the JLab IR FEL, energy recovery is emerging as a powerful application of RF superconductivity. The rest of the talk focuses on the accelerator physics and potential applications of superconducting rf, energy recovering linacs.
