Selective Chemical Pumping of Electronic States and Formation and Deactivation Processes in Electronic Transition Chemically Pumped Lasers.

摘要

A variety of high temperature techniques are applied to the study of visible chemiluminescent phenomena over the pressure range .000001 to 100 torr in order to assess the applicability of several reaction systems for the development of visible chemicals lasers. Efforts have focused on selective formation of excited electronic states, the nature of electronic state interactions and the behavior of these states over a wide pressure range. In studying chemiluminescent spectra, efforts have concentrated on the determination of activation energies for excited state formation, the determination of excited state quantum yields, the determination of approximate radiative lifetimes for long-lived states, the assessment of rapid energy transfer routes among excited electronic states and the analysis of collisional quenching. Promising systems have been and are being explored in an exploding wire laser system. (Author)
