| Abstract: | Features of the generation of the second optical harmonic in the heterostructures HgCdTe/GaAs and CdTe/HgCdTe/GaAs manufactured
by means of molecular-beam epitaxy are experimentally investigated for the first time. The dependences of the intensity of
a nonlinearly optical signal on the direction of the pumping radiation polarization and the position of the laser beam on
the study surfaces are measured for a pure monocrystalline substrate and for a sample with a deposited functional polycrystalline
CdTe layer. Substantial differences between these dependences are discovered. |
