  • Microstructure and Wear Resistance of Ni-Based WC Coating by Ultra-High Speed Laser Cladding
    Abstract: Steel materials are highly sourced construction materials owing to their robust mechanical properties, and they are widely used in the construction industry for building bridges, tunnels, skyscrapers, towers, ship-metal parts, and other industrial metal applications. However, as steel has poor surface wear resistance, parts are susceptible to failure due to friction damage. To improve th...

  • Hardfacing steel with nanostructured coatings of Stellite-6 by supersonic laser deposition
    Abstract: The ability to manufacture coatings is critical to engineering design. Many components require the application of additional layers to enhance mechanical properties and protect against hostile environments. Supersonic laser deposition (SLD) is a novel coating method based on cold spray (CS) principles. In this technique, the deposition velocities can be significantly lower than those req...

  • Low-loss single-mode hybrid-lattice hollow-core photonic-crystal fibre
    Abstract: Remarkable recent demonstrations of ultra-low-loss inhibited-coupling (IC) hollow-core photonic-crystal fibres (HCPCFs) established them as serious candidates for next-generation long-haul fibre optics systems. A hindrance to this prospect and also to short-haul applications such as micromachining, where stable and high-quality beam delivery is needed, is the difficulty in designing and ...

  • Research status of laser cladding temperature field simulation and characterization
    1.Influencing factors of temperature field in laser cladding During the laser cladding process, the temperature field has many influences, such as powder feeding rate, cladding layer thickness, spot diameter, scanning speed, etc. Use experimental methods to study thermal mechanisms or use equ ipment to detect molten pool temperature and coating stress distribution It is very difficult to wait, and...

  • Isolator-free unidirectional thulium-doped fiber laser
    Abstract: We report the first demonstration of a unidirectional, isolator-free 2-μm thulium-doped fiber (TDF) laser, relying on the properties of the theta cavity (ring resonator with S-shaped feedback). The core pumped theta cavity TDF laser provides sub-Watt output power with a slope efficiency of 25%, a 2 dB flat tuning range of 1900–2050 nm, and a linewidth of 0.2 nm, and achieves the extincti...

  • Robust and ultralow-energy-threshold ignition of a lean mixture by an ultrashort-pulsed laser in the filamentation regime
    Abstract: Laser ignition (LI) allows for precise manipulation of ignition timing and location and is promising for green combustion of automobile and rocket engines and aero-turbines under lean-fuel conditions with improved emission efficiency; however, achieving completely effective and reliable ignition is still a challenge. Here, we report the realization of igniting a lean methane/air mixture ...
