Multicore Optical Fibre TRIZ Cases
- Dual-Wavelength Radial-Mode Fiber Laser for Copper Welding
A green annular beam preheats copper while an infrared center beam melts it, improving weld quality with independent wavelength and power control.
- Multi-Core Fiber Alignment Control for Marker-Based Fusion Splicing
Marker-first alignment lets multi-core fibers be rotated and translated precisely before core matching and fusion splicing.
- Composite Laser Beam Welding for Uniform Penetration Control
A concentric center-and-ring laser beam with multi-wavelength output stabilizes penetration and reduces spatter and porosity in welding.
- Laser Beam Piercing with Spatter-Root Heating for Coated Workpieces
A dual-density laser beam heats spatter roots on coated workpieces to limit adhesion and preserve pierced-hole quality.
- Optical Fibre Squeezing for Adjustable Laser Beam Quality
A periodic fibre-squeezing mechanism varies beam quality on demand, improving laser cutting speed and edge roughness across metal thicknesses.
- Multi-Core Optical Fiber Beam Shaping for Laser Cutting and Welding
A dual-core fiber combines bright and broad laser modes to cut and weld thick materials with less seam hardening, deformation, and cleaner cuts.
- Composite Laser Beam Welding for Stable Aluminum Weld Seams
A concentric center-and-ring laser beam with wavelength spread stabilizes the melt pool and reduces porosity, spatter, and seam irregularity.
