High-Purity Ytterbium Metal (Yb) is a silvery-white rare-earth metal celebrated for its exceptional optical properties and role in high-power laser technologies. With a CAS number of 7440-64-4 and an atomic weight of 173.05 g/mol, this metal offers purity levels of 99.9%-99.995% (4N-5N), featuring a melting point of 824°C and a density of 6.97 g/cm³. Its unique ability to efficiently absorb and emit near-infrared (NIR) light, combined with excellent thermal conductivity, makes it indispensable in advanced optoelectronic and energy systems.
1. NIR Optical Efficiency: Yb³+ ions exhibit a wide absorption band at 980 nm and narrow emission at 1030-1060 nm, enabling high-energy laser generation with minimal thermal load.
2. Low Quantum Defect: The small energy difference between absorption and emission bands (26 nm) reduces heat generation, critical for maintaining beam quality in continuous-wave lasers.
3. Ductile Metallic Form: Easily drawn into wires (down to 50 μm diameter) and rolled into foils, facilitating integration into compact optical devices.
4. Oxidation Resistance: Forms a protective Yb₂O₃ layer in dry air, ensuring long-term stability in high-vacuum environments like space-based lasers.
5. Alloying Purity: Vacuum-melted to reduce oxygen (O <50 ppm) and nitrogen (N <20 ppm), optimizing magnetic and mechanical properties in alloyed systems.
• Fiber Lasers: Doped into silica fibers to create Yb³+-doped fiber amplifiers (YDFAs), boosting signal strength in long-haul telecommunications and data center networks.
• Solid-State Lasers: Used in Yb:YAG and Yb:YVO₄ crystals for material processing (e.g., precision cutting of carbon fiber composites) and medical applications (e.g., laser-assisted surgery).
• Optical Coatings: Sputtered as thin films on beam splitters and waveguides to enhance NIR reflectivity, improving energy efficiency in laser systems.
• High-Tech Alloys: Alloyed with aluminum and magnesium to create lightweight, high-strength materials for aerospace structures, reducing component weight by 15% without compromising durability.
• Research & Development: Serves as a reference material in X-ray spectroscopy and as a dopant in quantum dot systems for next-generation photovoltaic devices.
Q: Why is Ytterbium Metal preferred over Ytterbium Oxide in laser doping?
A: Metal-based doping ensures more uniform ion distribution in crystal growth, minimizing defects that cause light scattering.
Q: What is the maximum operating temperature for Yb-doped lasers?
A: Up to 350°C in air-cooled systems, thanks to the metal's high thermal conductivity (26 W/m·K) and efficient heat dissipation.
Q: Can it be used in terahertz (THz) generation systems?
A: Yes, Yb:YAG lasers are key components in THz emitters for security screening and non-destructive material testing.
Q: How is surface oxide managed in precision applications?
A: Pre-treated with argon plasma to remove surface Yb₂O₃, ensuring clean metal-to-metal bonding in high-reliability assemblies.
Q: What is the lead time for custom-shaped Ytterbium Metal components?
A: Standard shapes (ingots, rods) are available within 1 week, while custom-machined parts (e.g., precision targets) require 2-3 weeks for fabrication.
