| 105 & 106.5 Micron Core
Power Delivery Fibers Nufern’s specialty multimode step-index fibers are designed for compatibility with the majority of fiber-coupled, single emitter, diode-laser packages and support the diode laser power delivery market. These power delivery fibers are available in a 105/125 core/clad ratio in low and high NA versions and also in a 106.5/125 core/clad ratio with high NA. The 106.5/125 fiber features high temperature acrylate as a standard coating in order to meet the challenges of harsh environments and high pump powers demanded by today’s need for robust applications. Other fiber diameters and coatings are available upon request. Typical Applications • Fiber coupled diode lasers • Couplers and pump combiners Features & Benefits • 0.12, 0.15 and 0.22 NA — Compatible with majority of fiber-coupled, diode-laser packages • Exceptional geometric uniformity and core/clad concentricity — Ease of coupling to pump diodes Optical Specifications MM-S105/125-12A MM-S105/125-15A MM-S105/125-22A MM-S106.5/125-22HTA Operating Wavelength 800 – 1600 nm 800 – 1600 nm 800 – 1600 nm 800 – 1600 nm Core NA 0.120 ± 0.020 0.150 ± 0.020 0.220 ± 0.020 0.220 ± 0.020 OH Level Low Low Low Low Geometrical & Mechanical Specifications Cladding Diameter 125.0 ± 2.0 µm 125.0 ± 2.0 µm 125.0 ± 2.0 µm 125.0 ± 1.0 µm Core Diameter 105.0 ± 3.0 µm 105.0 ± 3.0 µm 105.0 ± 3.0 µm 106.5 ± 1.5 µm Coating Diameter 245.0 ± 15.0 µm 245.0 ± 15.0 µm 245.0 ± 15.0 µm 245.0 ± 15.0 µm Core/Clad Offset ≤ 3.00 µm ≤ 3.00 µm ≤ 3.00 µm ≤ 3.00 µm Coating Material UV Cured, Dual Acrylate UV Cured, Dual Acrylate UV Cured, Dual Acrylate UV Cured, High Temperature, Dual Acrylate Operating Temperature Range -40 to 85 °C -40 to 85 °C -40 to 85 °C -55 to 125 °C Short Term Bend Radius ≥ 12 mm ≥ 12 mm ≥ 12 mm ≥ 12 mm Long Term Bend Radius ≥ 25 mm ≥ 25 mm ≥ 25 mm ≥ 25 mm Prooftest Level ≥ 100 kpsi (0.7 GN/m²) ≥ 100 kpsi (0.7 GN/m²) ≥ 100 kpsi (0.7 GN/m²) ≥ 100 kpsi (0.7 GN/m²) |
