Pure KH2PO4 and zinc-doped KH2PO4 crystals were grown using a slow evaporation solution technique, with their structural details and optical properties analyzed through various methods. The study showed that the Zn-KDP crystal exhibited enhanced SHG efficiency and third order nonlinear optical parameters compared to KDP, with its laser damage threshold and dielectric response also investigated.
Pure (KH2PO4, KDP) and zinc (Zn2+) influenced KH2PO4 (Zn-KDP) crystal have been grown by slow evaporation solution technique. The structural details of grown crystals were determined by means of powder X-ray diffraction analysis. The incorporation of Zn2+ in KDP crystal has been qualitatively analyzed by virtue of energy dispersive spectroscopy. The paramount linear optical constant of pure and Zn-KDP crystals have been illustrated using the transmission data from UV-vis spectral analysis recorded within range 200-900 nm. Kurtz-Perry test reveals the enhancement of 1.55 times in SHG efficiency of Zn-KDP crystal with reference to KDP. First ever, third order nonlinear optical (TONLO) parameters of Zn-KDP crystal has been investigated using Z-scan technique. Laser withstanding limit of Zn-KDP crystal has been determined by laser damage threshold (LDT) study. The dielectric response of pure and Zn-KDP crystals has been investigated at different temperatures. Microscopic etching study was employed to evaluate the crystal quality of grown crystal.
