A high-contrast 6-J 3-ns pulse has been obtained from an injection mode-locked TEA CO/sub 2/ oscillator using an extracavity SF/sub 6/-He saturable absorber to suppress the prepulse energy to <1 ..mu..J and an intracavity semiconductor transmission switch to suppress postpulses. The techniques described in this paper will allow the frequency and transverse-mode control of an oscillator to be maintained to much higher powers than are presently possible.
