SPIE Photonics West 2025, San Francisco, CA, USA, Booth #4505, January 21, 2025
OFS, a global leader in innovative fiber optic solutions, proudly announces the launch of its Large Mode Area (LMA) Polarization Maintaining (PM) Erbium-Ytterbium (ErYb) optical fiber. Designed specifically for high-power LiDAR and free-space communication applications, this advanced fiber will be showcased at the 2025 Photonics West Conference.
Building on OFS’ proven high-power gain fiber portfolio—including the industry-leading DirectLase™ Premium Optica Fibers for 3kW+ output power—the new ErYb fiber sets a benchmark in performance and reliability. Its robust design enables consistent delivery of over 100W average power at 1550 nm, with a high TMI threshold and low photodarkening. The 25 µm core and 300 µm cladding architecture provide low non-linearities and exceptional beam quality, making it ideal for demanding applications.
Dr. Jeffrey W. Nicholson, Senior Engineering Manager at OFS, highlighted the fiber’s advanced capabilities: “This enhanced design minimizes higher-order mode (HOM) content, allowing for high output power suitable for applications such as ground-to-satellite communications and airborne LiDAR. Additionally, the highly manufacturable design and high-volume fabrication processes ensure consistent product quality without compromising performance.”
Key Features and Applications
- High-Power Operation: Reliable average power > 100W at 1550 nm
- Precision Design: 25 µm core and 300 µm cladding for superior beam quality
- Advanced Reliability: High TMI threshold and reduced photodarkening for long-term stability
- Versatile Use Cases: Ideal for high-energy pulsed fiber lasers, ground-to-satellite communications, and airborne LiDAR
