Thirty-two years after the first operation of the short wavelength free electron laser (FEL) at Stanford University, there continue to be many important experiments, proposed experiments, and user facilities around the world. Properties of FELs in the infrared, visible, UV, and x-ray wavelength regimes are tabulated and discussed.

The Naval Postgraduate School (NPS) has begun the design and assembly of the NPS Free-Electron Laser (NPS-FEL). The basic NPS-FEL design parameters are for 40-MeV beam energy, 1 nC bunch charge, and 1 mA average beam current, in an energy-recovery linac configuration. The NPS-FEL will make use of portions of the Stanford Superconducting Accelerator (decommissioned in 2007), in particular the injector system, Stanford/Rossendorf-style cryomodules and RF system. The injector will be gradually upgraded to improve beam properties and increase the injection voltage. Each cryomodule contains two 9-cell TESLA-type 1.3 GHz cavities, each cavity powered by an individual 10-kW CW klystron. As of April 2008, the injector system has been reassembled. We are working towards beam tests with the injector system, including upgrades to support photocathode experiments. This paper describes the basic machine and laboratory configuration, initial experimental plans, and current status of the overall program.
