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.
