Optical Harmonic

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 AgGa0.6In0.4Se2 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 CO2 lasers.

Second Harmonic Signal

A comparative study of the second harmonic generation in ZnO micro particles and nanorods has been experimentally studied by Kurtz technique using nanosecond pulsed Nd:YAG laser. The results have been theoretically explained by taking into account the quadrupole moment as well as surface nonlinearity. It was observed that the nanorods yield polarized second harmonic signal while the second harmonic signal obtained from the micro particles was unpolarized.
