The discharge conditions of the multi-atmospheric e-beam sustained Ar-Xe laser are investigated. It is observed that the quasi-stationary period of a laser pulse depends on the e-beam current, the discharge power deposition and the gas density. The laser efficiency can be as high as 8%.

Electronic processes are used on an ever expanding scale in modern electrical engineering. Yet there is one field where electronics still finds little application. Indeed, electronic processes are widely used in measuring instruments (cathode ray oscillographs, photocells, high-frequency measuring devices, amplifiers, etc.), in cybernetics (automation,

The 20-year-evolution of high-power laser diodes with a multitude of device designs that explore various practical applications is presented. The four major applications for high-power diode lasers, namely pumps for EDFAs, YAG rods, disk lasers and fiber lasers have a tremendous impact on the selection process in this evolution.

In order to obtain filters capable of handling very high power, the use of radial lines and uniform line discontinuities was investigated as the most promising approach. In this connection, it was necessary to consider equivalent circuit and interaction effects for H-mode radial line mated at each end to uniform TE 10 waveguide for taper angles of 45 ...
