The operating principle and features of the oscillating process for a three-wave CO2 laser with acousto-optic Q-switching are described. Optimization of the active-medium composition and its excitation conditions as well as the choice of oscillating lines allow oscillation with an output power up to 5 W per line in a stable multiwave mode to be obtained. An efficient Q-switching method for a three-wave CO2 laser is demonstrated and enables the output radiation to be controlled in both a wide spectral range and a wide range of modulation frequencies. A method for separating signals with different wavelengths by spacing signals in time has been experimentally implemented using an external selective modulator to simplify data acquisition and processing.
