The breakdown and the thermal nonlinear effect is studied in theoretical and experimental aspect. The breakdownthreshold of the air and water vapor also had been measure.
The results show: pulse power density from CO2 laser reaches air breakdownthreshold through thrice reflecting focus system, and plasma radiation phenomena is observed in the experiment.
