Typical Applications • Fiber coupled diode lasers • Couplers and pump combiners 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, singleemitter, 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. 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 • Pure Silica Core — High resistance to optical damage Optical Specifications Operating Wavelength Core NA OH Level Geometrical & Mechanical Specifications Cladding Diameter Core Diameter Coating Diameter Core/Clad Offset Coating Material Operating Temperature Range Short Term Bend Radius Long Term Bend Radius Prooftest Level 245.0 ± 15.0 pm < 3.00 pm UV Cured, Dual Acrylate -40 to 85 °C > 12 mm > 25 mm > 100 kpsi (0.7 GN/m2) 245.0 ± 15.0 pm < 3.00 pm UV Cured, Dual Acrylate -40 to 85 °C > 12 mm > 25 mm > 100 kpsi (0.7 GN/m2) 245.0 ± 15.0 pm < 3.00 pm UV Cured, Dual Acrylate -40 to 85 °C > 12 mm > 25 mm > 100 kpsi (0.7 GN/m2) 245.0 ± 15.0 pm < 3.00 pm UV Cured, High Temperature, Dual Acrylate -55 to 125 °C > 12 mm > 25 mm > 100 kpsi (0.7 GN/m2) fJUFERN 7 Airport Park Road, East Granby, CT 06026 • 860.408.5000 • Toll-free 866.466.0214 • Fax 860.844.0210 • E-mail info @ nufern.com • www.nufern.com • Nufern products are manufactured under an ISO 9001:2008 certified quality management system.
