Abstract
The development of the free electron laser (FEL) as a source of coherent
radiation continues toward the fulfillment of its potential for high power, high efficiency
and short wavelength. New experiments toward fulfillment of the FEL's potential
present new phenomenon to be studied by theoreticians and experimentalists. Two of
these phenomenon in short wavelength FELs are the shift in phase velocity resonance
and the reduction in gain. The first part of this thesis presents an argument for the use of the FEL in a
maritime military capacity. The advantages of the FEL over conventional kinetic
systems and other high-energy laser systems are emphasized.
The remainder of this thesis examines several effects of short wavelength FELs.
In particular, Chapter IV examines the characteristics of the proposed CEBAF UV FEL
and presents alternative designs to assist in design selection. Chapter V analyzes the
resonant phase velocity shift and loss in gain that occurs in short wavelength FELs
and presents a method to predict the resonant phase velocity and gain.
Chapter VI presents a new tool for examining the optical mode within the FEL.
By removing the input optical field from the total optical field, only the excited optical
field amplitude and phase remain. Chapter VI presents a modification to a
self-consistent three-dimensional simulation that will display the excited optical field.
