Summary: In this study, the identification of the orbital angular momentum modes based on spatial self-phase modulation in rubidium atomic vapor is presented. The refractive index of the atomic medium is modulated by a focused vortex laser beam, resulting in a nonlinear phase shift directly related to the orbital angular momentum modes. The output diffraction pattern exhibits distinguishable tails, with the number and rotation direction corresponding to the magnitude and sign of the input beam's orbital angular momentum, respectively. The visualization degree of the orbital angular momentums identification can be adjusted by the incident power and frequency detuning. These findings demonstrate that the spatial self-phase modulation of atomic vapor offers a feasible and effective way to rapidly readout the orbital angular momentum modes of a vortex beam.

Summary: The aim of this study was to investigate the properties of Azo-SR8, including its synthesis, characterization, and nonlinear optical (NLO) properties. Various methods, such as NMR, mass and absorption spectra, DSC thermogram, optimized structure, and investigation of frontier molecular orbitals, were used. The NLO properties of Azo-SR8 were analyzed using a cw laser beam and diffraction patterns (DPs) and Z-scan techniques, while the all-optical switching (AOS) capability was examined using two cw laser beams. The obtained results provide valuable insights into the potential applications of Azo-SR8 in optics.

Summary: The polarization state of light has an impact on nonlinear refractive index measurement. This study combines Mueller matrix polarimetry with z-scan technique to investigate the reciprocal effects of optical nonlinearity and polarization. Through classical Mueller matrix polarimetry, the polarization states are generated before the sample in the z-scan system and analyzed after the sample and before the closed aperture detector. The thermal nonlinear refractive index of an Azo dye, Janus Green B, was measured using a CW laser at a wavelength of 655 nm, and the results were found to be highly sensitive to polarization states. The measured Mueller matrix at each position of the sample resulted in a nonlinear dependence of the related Deattenuation, Retardance, and Depolarization parameters.

Summary: In this study, the photothermal nonlinearity within a layered bismuth telluride (Bi2Te3) was investigated in detail. The difference between the thermally-induced and photon-induced nonlinearities was clarified, and the entire photothermal nonlinearity was sketched. By removing the thermally-induced background signal, the n2 value without accumulated heat was estimated. The study also discusses the working range of the n2 value and provides validation through comparative measurements with another method.

Summary: The nonlinear refractive index of large area monolayer MoS2 thin film at the 1,550 nm wavelength band was determined using the time-resolved z-scan technique. The MoS2 film exhibited positive nonlinear phase shift with a large n(2) value of 1.40 x 10(-13) m(2) W-1. This value is similar to the n(2) value of monolayer MoS2 film measured at 2.0 µm and is orders of magnitude larger than silicon and common bulk dielectrics, indicating its potential as a nonlinear refractive 2D material for photonics applications in the 1,550 nm optical telecommunications wavelength band.

Summary: This study investigated the nonlinear photophysical properties of dopamine using the CA Z-scan technique and theoretical simulations. The results revealed that the nonlinear property of dopamine is governed by the thermo-optical effects, and the CA Z-scan profiles can be modulated by parameters such as phase-shift, orders of absorption, and time dependency. The findings contribute to the understanding of the relationship between nonlinearity and dopamine homeostasis and associated diseases.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

The introduction of Sb3+ effectively reduced the band gap of the host material and enabled energy transfer pathway for Tb3+ emission. The doped Tb3+ ions resulted in the suppression of emission due to electron transfer. The Cs2NaInCl6: 2.5 %Sb3+, 40 %Tb3+ NCs exhibited superior sensitivity and selectivity for copper ions detection.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
