Bookham, Inc., a provider of optical components for industrial applications, has launched a single emitter-based pump laser module capable of delivering 20W of fiber coupled power into a 105um, 0.15NA fiber. The product is designed to target fiber laser and direct systems for material processing applications, and will allow laser manufacturers to optimize their dollar per watt ratio.
The increased power output of the Bookham pump module enables customers to generate greater power levels for fiber laser pumping with fewer modules, allowing for more compact pump configurations, greater pump block efficiency and simplification of packaging.
"As we see new entrants into the already highly competitive fiber laser marketplace, cost will be an increasingly important factor for differentiation and the dollar per watt ratio is the key metric for all manufacturers," said Gunnar Stolze, Director of High Power Laser Marketing and Sales at Bookham. "With this increased power offering, we are enabling manufacturers who do not have their own internal pump laser diode technology to compete on both performance and price."
The new passively cooled, small form factor multimode pump module has a floating anode/cathode design and includes the latest generation of multimode pump laser chips from the Bookham Zurich facility. The robust coupling approach delivers more than 80% coupling efficiency and the module can operate at wavelengths from 795nm to 980nm, making it suitable for a variety of pumping and direct applications. The module is designed to include current and next generation single emitter laser chips, allowing customers to seamlessly upgrade their systems.
