 Jefferson Laboratory is in Newport News, Virginia and operates an Infrared Free Electron Laser of unprecedented  average power, since it uses superconducting radio-frequency cavities and re-circulates the electron beam.

The Jefferson Lab FEL is a sub-picosecond, tunable light source covering the range from 250 nanometers in the ultraviolet to 14 microns in the mid-infrared, with pulse energies up to 300 microJoules, and at repetition rates up to 75 MHz. Not all parameters can be satisfied simultaneously but average powers in excess of 10 kW have been demonstrated in the infrared.

We also have a high power THz laboratory whose source is the electron beam in the FEL.  This is a broadband source covering the range 0.1 - 5 THz and with an average power of 100 watts.

Here's a list of my publications.

Check out this Web Periodic Table with hyperlinks and which includes my list of the Binding Energies of the Elements, which is also available as a 24"x36" poster in power point, and for which I welcome any updates by e-mail, see address above. There are some very useful General Physics references.
