On the base of high photorfarctive parameters of the doped Sn P S crystals the four-wave mixing shemes are realized, partially the waefront conversion in the self-pumped ring-loop scheme, mutual phase conjugation, dynamical interferometer; their applicability for some technical tasks was demonstrated. A new lensless scheme of the image formation base on the two-wave interaction is proposed. The efficiency of the doped Sn P S crystals in the opto-acoustical testing (tomography) for the tasks of biomedical diagnostics was demonstrated. Product Description popup.authors Височанський Ю. М.
