Operational characteristics of a high power pulse preionized transverse-flow CO2 laser is discussed in derail. A new electrode configuration has been designed and the characteristics of discharge input power and output power are studied. The results show that the pulse preionization can significantly increase the input power and the output power of the lasers, and is proved to be a effective method for improving discharge stabilities and homogeneities of a high power CO2 laser.
