Abstract :
A tunable Q-switched/cavity-dumped partial Z-fold CO2 waveguide laser with two channels and common electrodes was designed. The Q-switched and cavity-dumped pulse lasers have been obtained from the Z-fold channel with a tunable pulse repetition frequency (PRF) of 1-70 kHz. At the Q-switched operation, the peak power is 730 W and the pulsewidth is 150 ns at the PRF of 10 KHz. At the cavity-dumped operation, the pulse laser width can be adjusted. The peak power is 6000 W with the pulsewidth of 20 ns and 3400 W for 32 ns. Continuous-wave laser output has been obtained from the other channel and its frequency can be tuned by a piezoelectric transducer. The Q-switched and cavity-dumped pulse laser heterodyne waveforms are observed. Meanwhile, six-temperature model was used to analyze the process of the dynamic emission in the electrooptically Q-switched CO2 laser. The theoretical results were well consistent with the experimental results
