Abstract:
Lasing on the third harmonic of the fundamental FEL wavelength has recently been accomplished. Lasing on even higher harmonics appears to be possible and can offer advantages of various kinds. A serious problem is the necessity for suppressing lasing on unwanted harmonics and selecting only the desired one. We have devised a technique to select the desired harmonic that depends upon a modification to the design of the wiggler. We discuss the principles of this modification, the properties of modified wigglers, and give an example of a wiggler design that employs this technique.
