Abstract
We measure the small-signal gain coefficient g 0 and the saturation-energy intensity E s of a gold-vapor laser by implementing an oscillator-amplifier on the base of the gold-vapor laser. The dependence of the gain and saturation properties of the laser on the length of the laser active medium, the buffer-gas pressure, and the buffer-gas type are studied. The measurements of g 0 for the amplifier for different lengths of the laser active medium (60 and 75 cm) show that with increase in the active-medium length, g 0 increases while E s, vice versa, decreases. Such behavior of g 0 and E s is observed in the whole range of changing the total pressure of buffer gas in the He-Ne mixture.
