ABSTRACT
This chapter examines the study and development of optical systems for the formation of high-quality single-beam radiation in copper vapour lasers (CVL) and copper vapour laser systems (CVLS): diffraction divergence and with stable parameters. One of the main differences between pulsed CVL and other types of lasers is the combination of a short time of existence of population inversion, commensurate with the radiation path in the resonator, with a large gain of the active medium. Experimental studies of the characteristics of pulsed CVL radiation in a single-mirror regime were carried out in the regime with a single convex mirror in the setup. Heating and excitation of active elements in the experimental CVLS provided a two-channel synchronized pulse power source containing two high-voltage rectifiers of the power source and two high-voltage nanosecond pump pulses based on water-cooled hydrogen thyratrons TG1-2000/35.
