“…The tendency of the molecules to become denser in the region exposed to intense light is known as electrostriction. This increases the absorption of the sample in that region, leading to RSA . The electrostriction effect has been observed in studies of nanomaterials. , However, as electrostriction is dominant in the case of dielectric materials, its effect in this experiment will be negligible.…”

Quantum dots of MoS 2 synthesized via the method of laser ablation show a mixed phase of 2H and 1T polytypes with a lateral size of 2−7 nm. The photoluminescence spectra exhibit prominent dependence on the energy of the incident photon. This observation indicates a distribution of energy bandgap and the presence of differently sized dots. This is also supported by the energy-dependent decay rates. The z-scan technique and optical phase conjugation geometry of degenerate four wave mixing are used to estimate the nonlinear optical parameters. The change in nonlinear optical response of the dots with the pump wavelength is also investigated. The mechanisms of two-photon absorption, electrostriction, free carrier refraction, free carrier absorption, and nonlinear scattering along with the laser-induced thermal effects are found to contribute to the nonlinear response. The effect of the mixed phase and nonzero direct bandgap, achieved via the quantum confinement effect, on the observed nonlinear optical response is discussed. The prepared dots show good optical limiting capabilities, which make them a promising candidate for designing protective coatings for high power lasers.

The sonochemical‐assisted multicomponent reaction catalyzed by ionic liquid, solvent‐free synthesis, improving chemical structure, computational calculations, and nonlinear optical properties (NLO) assessment of a new amidoalkyl naphthol derivative 4, that is, [N‐((2‐hydroxynaphthalen‐1‐yl)(4‐nitrophenyl)methyl)‐2‐phenylhydrazinecarbothioamide (C24H20N4O3S), are introduced. The corrected structure of the synthesized derivative 4 is confirmed by different spectroscopic techniques viz., (1H and 13C) NMR, Infrared radiation (IR), Mass spectra, and UV‐vis. spectra. To obtain geometrical structure and confirm the experimental findings, DFT‐assisted B3LYP/6‐31G* method is used. The NLO properties of the synthesized derivative are studied using two visible laser beams where its nonlinear refraction index (NLRI) at 473 nm cw laser beam is obtained using diffraction patterns (DPs) and the Z‐scan techniques. As high as 5.312×10−11 m2/W of NLRI is obtained. The all‐optical switching (AOS) which is usually carried out utilizing two laser beams, the controlling and controlled, is generalized by the use of three laser beams, controlling, 473 nm beam and two controlled 532 nm and 635 nm beams.
