Abstract
The CO2 laser group at the Institute of Laser Engineering, Osaka University is equipped for doing on the laser beat-wave acceleration experiment. By injection-locking with the 9P (22) line in a piezoelectric-controlled CO2 laser cavity, we have obtained a well-balanced double line oscillation of the 9P (22) and 10P (20) lines, that is to say, the shot to shot stability as for the double line balance is more than 90%. The total output is 300 J in 1 ns pulse. The energy and balance between two lines are suited for the beat-wave acceleration.
