摘要

In this work, second harmonic generation has been investigated for radiation in IR-range of spectrum at the constant-intensity approximation. The detailed analysis of nonlinear interaction of optical waves have been studied in CGA, ZAP and AgGa_(0.6)In_(0.4)Se_2 crystals and the comparison of the obtained results have been made on conversion efficiency with experimentally calculated values. The conditions for realization have been determined for the regime close to the uncritical angular phase matching. The recommendations are suggested on elaboration of the reliability of highly efficient generators for second harmonic in the IR-range, specially the generators of second harmonic of the CO_2 lasers.
