An electrooptically Q switched RF excited CO 2 waveguide laser is presented. The waveguide length is 400 mm. The cw output power of 3.5 W has been achieved with the electrooptic crystal without pulse voltage, mounted within the waveguide. The Q switched pulse repetition rate is 1 Hz～10 kHz. The peak power of 200 W and the pulse width of 400 ns have been obtained at the pulse repetition rate of 10 kHz.
