Abstract:
An in situ mass-spectrometric sampling technique has been developed for lifetime studies of TEA CO2 lasers. Using the new technique, an analysis of the gas components of a TEA CO2 laser during its lifetime has been performed. The results show that the laser output pulse energy was strongly influenced by the oxygen concentration inside the device.
