摘　　要：High repetition rate transversely exited atmospheric pressure (TEA) CO2 laser with randomly coded wavelength selection is suggested. The laser wavelength is tuned by a Fabry-Perot (F-P) etalon of low fineness, whose space interval is controlled by a piezoelectric transducer (PZT). A digital controlled programmable voltage source is introduced to vary the voltage applied on PZT so as to swiftly shift the laser output wavelength pulse by pulse. Detailed theoretical analysis is carried out by six-temperature mode rate equations.High repetition rate transversely exited atmospheric pressure (TEA) CO2 laser with randomly coded wavelength selection is suggested.
