Abstract
Energy characteristics of a copper vapor laser (CVL) pumped by a Marx generator are studied. The schematic of the generator is provided along with the description of its operational features, since thyratrons are used as switches in the generator. It is shown that the Marx generator allows an increase in the upper limit of stable operation of thyratrons (proportional to the number of thyratrons used, up to ~ 8-10 kV of reverse voltage on the thyratron anodes for two thyratrons) and, accordingly, provides pump parameters for the active medium that are unattainable with a single thyratron. At the same time, the energy per pulse linearly increases with the voltage on the gas discharge tube (GDT) and decreases with the repetition rate of the excitation pulses. A CVL pumped by a Marx generator is a promising radiation source for solving problems of atmospheric altitude sensing, creating artificial guide stars in adaptive optics devices and active optical systems, and atmospheric bistatic communication channels.
