Intra-Cavity Loss Element Method for Measurement of the Small Signal Gain of a TEA CO2 Laser

Abstract

The small-signal gain coefficient of a TEA CO 2 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.

An innovative method for plasma characterization of the spark pre-ionization pulsed TEA-CO2 laser

“…Among the different kinds of fabricated lasers, pulsed TEA-CO 2 lasers [1,2] have many applications in industry, science and medicine [3]. The characteristics of such lasers have been studied and developments have been made by researchers over the years [4][5][6][7]. The electron temperature and plasma density for the glow discharge of gaseous lasers are the most important parameters; the self-sustained glow discharge can be optimized to provide a higher efficiency of the laser system.…”
