OFS Unveils PM LMA ErYb 25/300 P Optical Fiber for High-Power LiDAR and Free Space Communication

SAN FRANCISCO, Jan. 21, 2025 /PRNewswire/ -- SPIE Photonics West 2025, Booth #4505 -- 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

OFS invites attendees to visit Hall F, Booth #4505 at SPIE Photonics West to learn more about this innovative fiber. Additional information about the PM LMA ErYb 25/300 P Optical Fiber is also available at www.ofsoptics.com/photonics-west.
