A small amount of hydrogen was added to neon buffer gas in a discharge-heated gold vapor laser. It was found that the output power and efficiency of the gold-vapor laser dramatically increased. The average output power and efficiency increased as much as 60%, when 0.5–1.0 Torr of hydrogen was added to neon. Maximum average power of 8 W was obtained using a plasma tube with 30 mm00D8×100 cm active volume.
