Description
Summary:2-amino-6-methyl pyridinium L-tartrate (2A6MPLT) was used to grow a new organic nonlinear optical single crystal. The 2A6MPLT crystal grew in an orthorhombic space group P2 1 2 1 2 1 crystal structure. The crystal morphology was investigated. The percentage of transmittance and optical band gap of the 2A6MPLT crystal were found to be 80% and 3.50 eV, respectively. The solid-state parameters of the grown crystals were examined. Surface laser damage threshold value of 2A6MPLT single crystals was measured to be 4.6 GW cm −2 at 1064 nm laser radiation. The photoconductivity study confirms the grown crystal is positive photoconductivity. The microhardness test was carried out employing 2-amino-6-methyl pyridinium L-tartrate crystal, and therefrom the hardness number (H v ), Meyer’s index ( n ), yield strength (σ y ) and elastic stiffness constant (C 11 ) were assessed. The dielectric behaviour of the grown crystal was studied for different temperatures at different frequencies. The 2A6MPLT had a SHG efficiency that was 1.42 times that of KDP and 0.312 times that of Urea. The Z-scan technique with an He–Ne laser at 632.8 nm was used to analyse the third order optical nonlinearity characteristics of 2A6MPLT and its suitability in NLO applications.
