Abstract

The beam characteristics from two 2kW CO₂ lasers coupled as an oscillator/amplifier pair is discussed with particular reference to the power gain and mode structure variations generated in the amplifier section. It was found that gain saturation, plasma saturation and beam clipping phenomenon were the dominant effects governing power amplification. The mode structure was essentially unaltered by the presence of a plasma in the amplifying section. Some alteration in the mode was noticed for high input powers from the oscillator due to clipping.
