An investigation of a discharge-heated barium laser

An investigation of a discharge-heated barium laser

Barium has been used as the working medium in a discharge-heated metal-vapor laser. The laser produced an average power of 12 W, principally at 1.5 μ, with an overall efficiency of 0.54% when operating at a pulsed repetition frequency (PRF) of 8 kHz. A parametric study of laser performance and a rol...

Zusammenfassung:Barium has been used as the working medium in a discharge-heated metal-vapor laser. The laser produced an average power of 12 W, principally at 1.5 μ, with an overall efficiency of 0.54% when operating at a pulsed repetition frequency (PRF) of 8 kHz. A parametric study of laser performance and a rollover in laser power at high barium number density are discussed.
