A high pressure 585.3 nm neon hydrogen laser
Abstract
Lasing was observed on the 3p' ( {1}/{2}) 0-3s'( {1}/{2}) 01 (i.e. 2p 1-1s 2 in the Paschen notation) Ne transition at λ = 585.3 nm in mixtures of Ne and H 2. A small (200 mm active length), Blumlein type, transverse-discharge driven assembly delivered laser pulses with fwhm between 30 and 140 ns at pressures of up to 700 mbar. The population inversion is ascribed to a fast Penning reaction between H 2 and Ne which effectively depopulates the lower laser level.
