Pioneering Quasi-Continuous Wave (QCW) Fiber Solutions for High-Reflectivity Precious Metals, Advanced Micro-Fabrication, and Automated Jewelry Manufacturing.
Explore our custom factory configurations engineered for precision mold repair, delicate metallurgical crafting, and rapid production cycles.
The international micro-joining sector is experiencing an unprecedented structural transition from flashlamp-pumped solid-state Nd:YAG resonators to Quasi-Continuous Wave (QCW) fiber laser architectures.
Conventional flashlamp systems deliver wide beam divergence and high thermal collateral impact, often resulting in annealing soft spots or micro-cracks adjacent to delicate gems. QCW fiber delivers electro-optical conversion exceeding 30%, single-mode beam quality (M² < 1.2), and a micrometer-scale spot size that eliminates thermal stress on diamonds, emeralds, and organic stones.
Gold (Au), Fine Silver (Ag), and Copper (Cu) alloys exhibit optical reflectivity rates exceeding 90% at standard 1064nm wavelengths. Our factory’s custom QCW architectures offer transient peak pulse powers up to 10× their nominal average power, instantly vaporizing surface oxide boundaries, overcoming back-reflection hazards, and forming uniform, deep-penetration keyholes without surface pitting.
Traditional pulsed YAG machines require frequent flashlamp replacements, deionized water conditioning, and delicate resonator realignment every 800 to 1,200 operating hours. Youmir Laser’s monolithic all-fiber QCW architecture operates up to 100,000 maintenance-free diode hours, minimizing workshop operational expenditures across overseas jewelry studios.

| Performance Vector | Custom QCW Fiber Welder | Traditional Lamp-Pumped YAG | Production Value Factor |
|---|---|---|---|
| Wall-Plug Efficiency | 30% – 35% | 2% – 4% | 85% reduction in electrical power overheads |
| Beam Quality (M²) | < 1.2 (Diffraction Limited) | 10 – 20 (Multi-mode Profile) | Ultra-clean seams, no spatter onto polished surfaces |
| Focal Spot Minimum | 0.05 mm (50 μm) | 0.20 mm – 0.30 mm | Feasible for 0.1mm micro-prongs & micro-chains |
| Optical Lifespan | Up to 100,000 Operating Hours | 1,000 – 1,500 Hours (Xenon Lamp) | Zero consumable costs; persistent factory uptime |
| Thermal Infiltration | Sub-millisecond localized impulse | Broad peripheral thermal spill | Weld directly beside emeralds, pearls & opals safely |
From boutique atelier benches in Vicenza and Antwerp to automated tier-1 luxury lines in Shenzhen and Dubai.
Enables seam-free ring sizing, porosity-free cast repair, clasp fabrication, and micro prong rebuilding on platinum (Pt950), yellow/white/rose gold (14K-24K), and 925 sterling silver without dismounting heat-sensitive gemstones.
Addresses Swiss horological demands for joining complex watch bezels, exotic titanium cases, balance-spring pinning, and hermetic micro-casing without mechanical deformation or internal component magnetism.
Expands past adornments into cobalt-chrome (Co-Cr), nickel-free orthodontic frames, and titanium dental implants where hermetic purity, non-oxidation, and zero-impurity joint integrity are mandatory under regulatory frameworks.
Shenzhen Youmir Laser Technology Co., Ltd. builds custom hardware, machine-vision algorithms, and modular automation lines directly in-house.
