Inductive Penning plasma neon laser with a wavelength of 585.3 nm

A pulsed inductive Penning plasma laser based on neon with lasing on a wavelength of 585.3 nm was created for the first time. The active medium was pumped by a pulsed inductive cylindrical discharge. Lasing was observed in the afterglow and was obtained only in a mixture of neon with hydrogen. The duration of the optical laser pulses reached 180 ns Full Width at Half Maximum (FWHM) and about 400 ns near the base. The laser beam had a ring form with a diameter of about 42 mm and a width of 2.5 mm. The measured lasing divergence did not exceed 2 mrad.
