Tunable single‐longitudinal‐mode operation of a transversely excited atmospheric (TEA) CO2 laser has been achieved using an injection technique with a cw waveguide laser as the master oscillator. Tunability in excess of 300 MHz from the CO2 line center is reported for various CO2 lines. A high resolution spectrum of an ozone absorption feature has been recorded using this technique.
