摘要：

In this work two multimegawatt, tail free, ns pulse CO2 lasers, with 2% efficiency are described. The lasers operate in a high gain (6% cm-1), high pressure (2 bar), He free mixture, with large outcoupling. In this way, after an intense power pulse, the residual pin is insufficient to sustain a tail emission. All the emission parameters (fluence, pulsewidth) can be predicted by means of a simplified theory. The optical damage limits the pulsewidth to approximately 8 ns.
