Harmonic Generation at Duke Free Electron Laser Lab

Emily Longhi

In this talk, I will start with a basic overview of how the OK-4 FEL works (it's basically just a giant light bulb).  I will describe the operational parameters of the machine and their current limitations (what colors we can see), and discuss how the FEL capabilities will be extended by the production of harmonics (how to make more colors). There will be a brief description of the mechanism for harmonic production and then I will show some recent data (it works!).
