Abstract

The energy extraction from a TEA CO₂ laser amplifier is optimized by using both multiline and multiple-pass amplification techniques. Special care was taken to keep the beam profile Gaussian. Multiple-pass amplification appears to be the best way to a significant increase in energy extraction efficiency. A maximum amount of energy of 9.7 J/ℓ was extracted at an efficiency of 4.3%, both values with respect to the volume of the beam inside the amplifier.
