Abstract
In order to prevent observed long-term energy decay of power amplifiers and correspondingly increase the lifespan of CO2 lasers employing them, a hydrogen-doped mixing gas is supplied from an external pipeline during operation or periodic maintenance in order to effectively remove solid contaminants that build-up over time on a surface of a catalyst disposed within the power amplifier.
