Laser action on the <i>B</i>2Σ+1/2→<i>X</i>2Σ+1/2 band of HgCl at 5576 Å

Abstract

This letter describes a new laser operating on the B2Σ+1/2→X2Σ+1/2 band of HgCl at 5576 Å. Pumping was achieved by high-intensity electron-beam excitation of high-pressure rare-gas mixtures containing small amounts of Hg and CCl4. A lower bound to the efficiency was determined to be 0.5% in an unoptimized configuration, and higher efficiency is expected.
