Middle infrared and deep ultraviolet laser systems, which are based on high-power high-beam-quality stable-operating He-SrBr₂ and Cu⁺ Ne-CuBr lasers excited in nanosecond pulsed longitudinal discharge, are developed, patented and studied. Optimal discharge conditions, such as active zone diameter, vapor pressure, buffer-gas pressure, electrical excitation scheme parameters, average input power, pulse repetition frequency, are found. The highest output laser parameters are obtained for the Sr atom and Cu⁺ lasers, respectively. These lasers equipped with optical systems for control of laser radiation parameters, such as laser beam divergence, laser intensity distribution, etc. are used in a large variety of applications, such as precise material microprocessing, including biological tissues, determination of linear optical properties of different materials newly developed, laser-induced modification of conductive polymers, laserinduced fluorescence in wide-gap semiconductors, instead of free electron and excimer lasers, respectively.
