a miniature CO2 laser that adopting acousto-optically Q-switched and grating tuned approaches is described
which pulse repetition frequency (PRF) is 1 Hz~50 kHz and the tuned wavelength range is 9.2 μm~10.8 μm. The pulse width of 180 ns and the peak power of 4062 W have been obtained at the wavelength of 10.6 μm when PRF is 1 kHz. The calculated results of laser rate equations are in good agreement with the experimental values.
