Multifrequency lidar based on dye laser

The transceiving system of a field version of the Gloriya multi-frequency lidar employed for atmospheric sounding at four wavelengths simultaneously is described. The transmitter employed is based on an organic dye laser. The technical specifications of the device are presented. Test results are discussed, and the aerosol backscattering coefficient obtained is plotted as a function of wavelength. The device continues to be improved, and a special multichannel system for data recording and processing is being developed.
