Abstract

An active volume scaling in bore and length of He-SrBr₂ laser excited in nanosecond pulsed longitudinal discharge is carried out. The optimal temperature regime is found for laser oscillation at several different Sr atom and ion lines. Optimal discharge conditions, such as active zone diameter, vapor pressure, buffer-gas pressure, electrical excitation scheme parameters, average input power, pulse repetition frequency, are found. At multiline operation a record average output power of 4.30 W for the Sr atom lasers is obtained, more than 90 % of which is concentrated on the 6.45-μm Sr atom line. A new discharge tube with furtherly increased active volume in bore is developed. The effect of neon additive to the helium buffer gas on the gas and electron temperatures is investigated.
