Abstract

Many intense neutral atomic fluorine laser lines in the visible (λ=7037.5–7552.2 Å) have been obtained from a gas mixture of F₂ and He at total pressures up to 3 atm, driven by a fast Blumlein discharge. At high pressures, three new laser lines have been found and were assigned to the quartet manifold: 7425.7 Å (3p⁴P⁰_1/2→3s⁴P_3/2), 7482.7 Å (3p⁴P⁰_3/2→3s⁴P_3/2), and 7515.0 Å (3p⁴P⁰_1/2→3s⁴P_1/2). The number of lines observed and their relative intensities were found to depend strongly on the pressue of the F₂/He gas mixture.
