Luminescent Characteristics Study of Mather-Type Dense Plasma Focus and Applications to Short-Wavelength Optical Pumping

摘要

A Mather type dense plasma focus (MDPF) system was designed, built, and tested specifically to study its luminescent characteristics and to assess its potential as a new light source of high energy, short wavelength lasers. The luminescence study of MDPF showed that the conversion efficiency from the electrical input to the optical output energies is at least 50%, up to the time the plasma compression is complete. Using the system, for the first time as an optical pump, laser activities were successfully obtained from a variety of liquid organic dyes. Diagnostic capabilities included an optical multichannel analyzer system complete with a computer control, a nitrogen pumped tunable dye laser system, a high speed streak/framing camera, a digital laser energy meter, voltage and current probes, and a computer based data acquisition system.
