Abstract

The subject of this thesis is the study of liquid dielectric transmission lines and their potential application as an excitation source in high speed, high-repetition rate laser designs. The design problems associated with the construction of high repetition rate (khz), short wavelength lasers have been reviewed and the major shortcomings of conventional electrical driving circuits identified. The identification of these shortcomings and a review of the available literature on electrical circuits for various types of lasers suggested that liquid dielectrics and transmission lines could potentially have significant advantages over more conventional circuitry used in high repetition rate, short wavelength lasers. The construction of a set of three parallel electrode, liquid dielectric transmission lines was undertaken along with the associated electrical circuitry necessary for efficiently charging the system. The resulting electrical driving network was capable of delivering high voltage, 50 nsec square wave current pulses at repetition rates exceeding 1 khz. The major problems limiting the practical usefulness of the system include the design tolerances required of the electrode separation structure and the requirements for a circulation system to deionize and decontaminate the liquid dielectric in designs requiring high reliability of the electrical driving circuitry.
