Abstract
We report the results of experimentally investigated dependences of temporal, spectral and spatial characteristics of an inductive HF-laser generation on the pump conditions. Gas mixtures ( or ) and ( or ) were used as active media. The FWHM pulse duration reached . This value corresponded to a pulsed power of . For the first time, the emission spectrum of an inductive HF laser was investigated, which consisted of seven groups of bands with centres around the wavelengths of 2732, 2736, 2739, 2835, 2837, 2893 and . The cross section profile of the laser beam was a ring with a diameter of about and width of about . Parameters of laser operation in the repetitively pulsed regime were sufficiently stable. The amplitude instability of light pulses was no greater than 5 % – 6 %.
