We report the design, and broadly tunable operation, for the first time, of a high average power free-electron laser using edge-outcoupling. Using the FEL in this configuration, we achieved a maximum stable output power of 270W at 2.53 μm, and could tune with an output of 20 W or higher from 0.8 to 4.2 μm. The output was in the form of a continuous train of sub-ps pulses at 4.68 MHz. Measurements of gain, loss, and the output mode are compared with models.
