Photodissociation Dye Laser Studies and High Pressure Discharge Conditioning Studies
Abstract
This report presents results on two distinct topics of investigation. The first phase of our study, covering a period of 1-1/2 years, represents a 'proof of principle' effort to develop a new class of tunable liquid lasers operating in the visible region of the spectrum. The idea, termed the Photodissociation Dye Laser (PDL) concept, relies on laser action occurring between an excited electronic state and the ground electronic state of radicals produced by the photodissociation of specific classes of organic molecules in solution. For the purposes of this investigation, five promising candidates for the PDL active media were synthesized from a group of molecules known as the hexaarylethanes. Fluorescence measurements were performed on these molecules to assess their use as laser media. Chemical reactivity problems associated with hexaphenylethanes were also investigated. The second phase of this study investigated the applicability of thermionic emission to sustain a long pulse, spatially uniform electrical discharge in high pressure (pd values = or > 1000 torr-cm) laser media.
