Abstract
The process of periodic structure formation on the GaAs surface by laser induced wet etching has been investigated. The exponential growth rates of the structures were measured in situ for the first time. The influence of the various etchants on the relief spectrum has been studied. Phased diffraction gratings with controled periods in 0.35-0.5 μm range have been obtained. The physical mechanism of this phenomena was established by the comparison of the theoretical and experimental results.
