Abstract

Recent advances in injection mode locking and high-power 10-μm pulse selection have been incorporated into a high-power CO₂ laser system built around a single five-liter TEA CO₂ gain module. A pulse selected from a line-tuned [to P(20)] injection-mode-locked oscillator was amplified to produce a 20-J, 3-nsec pulse with a main-pulse-to-prepulse contrast ratio of >10⁷:1.
