The small-signal single-pass gain for 24 individual CO laser lines has been measured for a flowing CO-air-He laser. The vibrational-rotational lines considered were for rotational transitions from to 16 and upper vibrational levels from to 11. The maximum gain was observed for the laser line, with an average logarithmic energy gain of cm-1.
