Z-scan screening of proton-shifted monohydrated organic salt: the linear, nonlinear, and optical limiting characteristics for photonic applications

Abstract

In the present decade, the advancement in photonic applications has stimulated the scientific community to explore nonlinear optical characteristics of optical materials. The present report on the synthesized proton-shifted monohydrated organic salt (ABMPP) of 2-Amino-5-bromo-6-methyl-4-pyrimidinol (ABMP) and 2,3-pyrazinedicarboxylic acid (PDCA) explores the linear and nonlinear optical (NLO) characteristics. The linear optical characteristics of ABMPP dissolved in DMSO have been investigated using the recorded absorption and photoluminescence spectra. In addition, the 1 H-NMR analysis has been executed for structural characteristics. The third-order nonlinear optical characteristics of the sample have been measured using the Z-scan technique with a 520 nm laser beam of CW diode laser. The coefficients of nonlinear absorption (b), nonlinear refraction (n 2 ) with nonlinear optical susceptibility, v (3) , and second-order hyperpolarizability (c) have been estimated for various solution concentrations and laser powers. The evaluated b, n 2 , v (3) , and c are found to be of the order of 10 -4 cm/W, 10 -8 cm 2 /W, 10 -6 esu, and 10 -26 esu, respectively, and these parameters vary linearly with solution concentration as well as laser power. The NLO performance of the ABMPP compound reveals its potential in photonic and optoelectronic applications. Furthermore, the compound has been also assayed for optical limiting characteristics with the same radiation and it shows comparatively better limiting performance. Hence this material could be a viable candidate for optical limiting devices.

A newly synthesized organic chromophore (HCzN) showing optical linear and nonlinear response for potential in photonic applications

“…where the quantity ΔT P−V is the difference in the peak-valley normalized transmittance. The nonlinear refractive index (n 2 ) and absorption coe cient (β) are calculated by tting the normalized transmittance curve with the following equations respectively [7] The dependency of NLRI (n 2 ) and NLAC (β) on the concentration represented in Table 1 reveals that the magnitude of n 2 , β, χ (3), and γ varies almost linearly with concentrations that have been evaluated using the relations reported in previous articles [5,6,9,10]. The variation in these parameters occurs due to the thermal lensing effect.…”

An experimental and DFT investigations of fused ring anthracenyl chalcones with effective modification in acceptor moiety: Nonlinear optical and optical limiting response

“…AC1 (4.56 Â 10 À10 cm 2 /W) exhibits superior NLR behavior when compared to AC2 (3.29 Â 10 À10 cm 2 /W) and AC3 (4.31 Â 10 À10 cm 2 /W), respectively. The presence of π bonds in the aromatic benzene rings increases intermolecular charge transfer inside the orbital itself, enhancing the compounds' nonlinear behavior [28,30]. The peak and valley characteristic suggests that the compound is self-defocusing due to its negative nonlinear refractive index, n 2 .…”
