Abstract
A coherent Doppler lidar based on a single-frequency injection-locked TEA CO2 laser is described. To satisfy the requirements to the radiato rs of Doppler TEA CO2 lidars, we optimized the composition of working gas mixture and the durations of pump current pulse in order to obtain a minimum bandwidth of generated radiation for a fixed output energy. Using a model describing real temporal and spectral parameters of the probing laser pulse, we measured the wind velocity profiles along hor izontal and vertical paths up to 10 km long.
