Summary: This paper presents a method for generating a 355 nm UV quasicontinuous pulse laser using two PPMgLN crystals in a single-pass cascade. The first crystal converts the 1064 nm laser to a 532 nm second-harmonic light, while the second crystal combines the 532 nm laser with the remaining 1064 nm laser to achieve a 355 nm UV laser. The achieved laser has high peak power and single pulse energy, making it an important application of PPMgLN crystal. This paper provides a significant case for realizing a 355 nm UV quasicontinuous or continuous laser.

Summary: In this study, we developed a compact and efficient diode-pumped solid-state ultraviolet laser at 355 nm with high commercial value. We used an uncoated Brewster-cut LBO crystal to couple out the 355 nm laser and extend its lifetime. The maximum output power achieved was 12.2 W with a pump power of 74.5 W and a pulse repetition rate of 40 kHz. The conversion efficiency from pump laser to ultraviolet laser was 16.4%, the highest reported for pump sources at 887 nm. The stability of the 355 nm laser power was within +/- 1% at 12 W over a duration of 20 hours. The study also investigated the output characteristics of the ultraviolet beam under varying temperatures of two LBO crystals to determine the optimal operating temperature.

Summary: This study focuses on the production and investigation of NiFe2O4 spinel ferrite nanoparticles doped with different masses of Se. The results show that the chemical content of Se has an impact on the crystal structure, microstructure, and magnetic properties. Superparamagnetic and ferrimagnetic states are observed in a wide magnetic field range. The magnetic characteristics do not change significantly when Se-substitution is less than 2.0%. However, a nonlinear dependence of magnetic parameters is observed for samples with Se-substitution greater than or equal to 2.0%. The undoped sample and NiFe2O4+x%Se exhibit soft magnetic behavior.

Summary: This paper presents the synthesis, physical characterization, and antibacterial properties of copper nanoparticles (CuNPs) incorporated in activated PVA/PMMA/montmorillonite (MMT) polymeric clay composites. The CuNPs were prepared using an eco-friendly solvent evaporation technique. The UV-Vis spectral analysis showed that the optical band gap energy of the composites could be adjusted by controlling the CuNPs loading, making them suitable for optoelectronic applications. XRD analysis confirmed a strong interaction between CuNPs and the polymeric clay composite. The composites exhibited improved hydrophobicity and excellent bactericidal activity, suggesting their potential use in the food packaging industry.

Summary: The use of electromagnetic (EM) devices has become widespread in various fields, but it also brings about issues such as signal pollution and radiation. To tackle these problems, researchers have been working on developing electromagnetic wave absorbing and shielding (EMAS) materials. However, most of the reported materials only possess the EMAS property. In practical applications, materials with excellent tunable absorption bands are needed. This review focuses on different external field-responsive materials and provides a detailed summary of various action mechanisms, materials synthesis methods, and macrostructures. The future trends in developing novel external field-responsive materials are also discussed.
