Paper Abstract

Sum frequency generators of Er3+:CaF2 ((lambda) equals 2.76 micrometers ), Er3+:YAG ((lambda) equals 2.94 micrometers ), and cw CO2 lasers with ZnGeP2 single crystals has been developed to enlarge the possibilities of spectroscopic systems based on CO2 lasers. The generated spectra overlapped the ranges from 2.0 to 2.4 micrometers , which coincide with the two main atmosphere transparence windows. The energy efficiency of sum frequency generation is about 3% at phase-matching angle of 52 degree(s). The results of numerical simulation of the high-altitude profiles definition of atmospheric meteorological parameters by differential absorption lidar system working in eye-safe spectrum range at 2 micrometers has shown, that errors of the temperature and humidity profiles restoring have reasonable values in all altitude range 0 - 2 km.
