Coherent Diode Lasers FAP FAP 8-LB Series Long-Bundle Fiber Array Packages Fiber Array Packages (FAP ) from Coherent are the highest quality fiber-coupled diode lasers in the industry, offering you the simplest way of delivering the output from a diode laser bar to your application. The FAP 8-LB (long bundle) consists of a 19-element conduction-cooled diode laser bar, lensed and coupled to an 8 µm, multimode fiber bundle array. FAP 8 products deliver the highest efficiency and reliability, by utilizing the highly efficient material structure and proprietary packaging techniques from Coherent. With their high brightness, compact size, and ease of integration, FAP 8 products are the ideal solution for a host of industrial, medical and pumping applications. The FAP 8-LB provides a fiber bundle typically 1 meter long that terminates in a SMA-95 connector. This design provides increased fiber flexibility for tight system design requirements and allows for inclusion of an integrated aiming beam. A vertically integrated manufacturer, Coherent is the industry leader in aluminum-free diode lasers and systems for commercial, defense and medical applications. At Coherent, we are a customer-driven company, where you are assured of reliable, high-performance diode lasers manufactured to meet your specific needs.

ESD precautions must be taken when handling unit. Negative current transients greater than 25 µa, and/or reverse voltages >3V, can destroy the unit. Unit requires an adequate heat sink. Failure to use an adequate heat sink will destroy the unit. Recommended heat sink flatness <_5 µm. A dry environment should be provided when storing or operating this device at temperatures below the ambient dew point. Failure to do so will cause condensation on the unit and can destroy it. Output powers in excess of specification will accelerate device aging. Operation at higher temperatures will accelerate device aging, increase threshold current and lower slope efficiency. Care should be taken to avoid back-reflections into the device. Failure to do so can destroy the unit.
