摘要：

A multi-wavelength fiber based MOPA-system is proposed to increase performance of coherent Doppler lidar systems. The setup of the four-wavelength lidar system is described and characterized. We show that the speckle patterns of each wavelength are uncorrelated. The measured Goodman's M-parameter is 3.8 for four wavelengths, using hard target reflections. Atmospheric measurements show uncorrelated speckle patterns as well. Consequently, the precision of the measured wind velocity can be improved by a factor of two.
