The small-signal gain coefficient of a TEA CO2 laser has been measured through the implementation of a variable polarization intra-cavity loss element. Charging voltage dependence of the gain property of the laser has been investigated. The advantage of this method is that no probe laser system is required. The results have been agreed with experimental data obtained by conventional oscillator-amplifier method.
