Operation of the sapphire Cerenkov laser

Operation of the sapphire Cerenkov laser First operation of a sapphire‐based Cerenkov free electron laser is reported. It is a tunable source of coherent millimeter and submillimeter radiation. The phase velocity of light in sapphire is about one‐tenth of that in free space so that Cerenkov radiation is obtained at modest electron beam energies. In addition to its role as a Cerenkov coupler, the sapphire forms a high Q resonator obviating external mirrors. The spontaneous Cerenkov emission is well‐confined by this resonator and can build to watts of power. Measured tuning and threshold currents are presented and compared with the predictions of free electron laser theory. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Physics Letters American Institute of Physics
