In this paper, we first achieve nanosecond-scale dissipative soliton resonance (DSR) generation in a thulium-doped double-clad fiber (TDF) laser with all-anomalous-dispersion regime, and also scale the average power up to 100.4 W by employing only two stage TDF amplifiers, corresponding gains of 19.3 14.4 dB, respectively. It is noted that both oscillator amplification system employ as gain medium for utilizing advantages high-gain-availability, high-power-handling...
The detection of molecules from highly diluted solutions with a limited amount is vital for precancer diagnosis, food safety, and forensic analysis. sensitivity convenience techniques are the primary concerns. In this study, hybrid superhydrophobic/-philic (SH/SHL) microporous platform designed fabricated by femtosecond laser to improve surface-enhanced Raman scattering (SERS) performances. Relying on micropores at center SHL patterns, sediments distributed central regions avoided, leading...
Ultratrace molecular detections are vital for precancer diagnosis, forensic analysis, and food safety. Superhydrophobic (SH) surface-enhanced Raman scattering (SERS) sensors regarded as an ideal approach to improve detection performance by concentrating analyte molecules within a small volume. However, due the low adhesion of SH surfaces, droplet is prone rolling, making it hard deposit on predetermined position. Furthermore, sediment with very area SH-SERS surface difficult be captured even...
Urban traffic accidents have become more common in recent years due to the rising number of motorized vehicles, climate change, and outdated subsurface drainage systems. Traditional road disease detection methods involve collecting data using ground-penetrating radar manually analyzing data. This process is time-consuming subjective. Deep learning, especially convolutional neural networks (CNNs), has proven highly effective image recognition object detection. By applying these techniques...

In this paper, we demonstrate a simplified one-to-many scheme for efficient mid-infrared (MIR) parametric conversion. Such is based on continuous wave (CW) single longitudinal mode master oscillator power-amplifier (MOPA) fiber system as the signal source and picosecond pulsed MOPA system, exhibiting multiple modes, pump source. The beams are combined co-coupled into piece of 50-mm long 5% MgO-doped PPLN crystal As high ∼3.82 W average power at central idler wavelength ∼3.4 µm achieved when...
Titanium alloy components often experience damage from impact loads during usage, which makes improving the mechanical properties of TC4 titanium alloys crucial. This paper investigates influence laser scanning irradiation on tensile thin sheets. Results indicate that strength sheets exhibits a trend initial increase followed by decrease. Different levels enhancement are observed in elongation at break cross-section. Optimal improvement is achieved when fluence around 8 J/cm2, while maximum...
The process of forming metal components through selective laser melting (SLM) results in inherent spherical effects, powder adhesion, and step which collectively lead to surface roughness stainless steel, limiting its potential for high-end applications. This study utilizes a laser-electrochemical hybrid polish SLM-formed 316L steel (SS) examines the influence parameters such as power scanning speed on micro-morphology. A comparative analysis roughness, microstructure, wear resistance SS...
