A UV laser based on the nitrogen molecule excited by a high-current discharge sliding over a dielectric surface
Abstract
A sliding-discharge pumping scheme for a UV nitrogen laser is described. In the experiment reported here, a sliding discharge was generated on a 1-mm-thick polished plate of crystalline leucosapphire over an area of 750 x 44 sq mm. It is shown that UV emission takes place in a thin layer (less than 1 mm) and that the emission is characterized by low divergence and high power density. Emission at the self-terminating transition of the neon atom (wavelength, 540 nm) was also observed in this scheme.
