Electron-beam-controlled gas lasers: discussion from the engineering viewpoint. Part II. Problems in the electrical design of very high energy systems

Some problem areas in the design of very-high-energy electronbeam- controlled short-pulse gas lasers are discussed. One of the prime areas of interest is the high-voltage pulse generators for driving the electron gun and gas pumping. The use of pulse-forming networks for improving energy-transfer efficiency is discussed. The use of thermionic cathode devices will require a large ac power installation. The properties of alternate electron sources (cold cathode and plasma cathode devices) are reviewed. The impact of laser beam energy density limitations on system geometry and electrical design are discussed last. (auth

Electron-beam-controlled lasers: discussion from the engineering viewpoint. Part I. Design of the 1 kJ and 10 kJ COsub2sub 2 lasers

The Los Alamos Scientific Laboratory (LASL) CO/sub 2/ laser program was organized to design, fabricate, and evaluate highenergy, short-pulse CO/sub 2/ lasers for use in fusion studies. A general discussion of electron-beam- controlled lasers is included, along with details of component designs. This includes a discussion of the high-voltage pulsers, electron guns, pumping chamber vessels, timing, and operational experience with the 1-kJ CO/sub 2/ laser system components. In addition, the general design of the 10-kJ C0/sub 2/ laser system is presented. (auth
