Brief Description of Technology
The project has to do with the research of problems in basic laser physics.

The objective of this project is to elaborate the experimental and theoretical foundations for the creation of a new type of high-efficiency discharge laser. These lasers are pumped by runaway kilovolt (up to a several dozens of kilovolts) electron beams generated directly in the active medium with the help of special configuration discharges. The theoretical research and the first experimental results of the metal vapor lasers (MVLs) pumped by gas discharge of this type predict a significant increase (by 1 - 2 times) in the efficiency and specific power of the existing MVLs and the creation of laser action over new lines of atoms, molecules, and ions in the ultraviolet, visible and infrared spectrum range.

The specific characteristics of such lasers in visible range can reach 1 kW per meter of length of an active zone with a physical efficiency of 5 - 6 % [1-3]. The first step in the creation of a new laser family within the framework of this project will be the elaboration of the MVL infrared spectrum range (Pb - and Eu-lasers).
