Bookham Introduces 25W Multi-Emitter Fiber Laser Pump Module

SAN JOSE, Calif., Jan. 27 /-- Bookham, Inc. (NASDAQ: BKHM), a provider of optical components for industrial applications, has launched a high power multi-emitter pump module capable of delivering 25W out of a 105um fiber with 0.15NA. The product meets fiber laser manufacturers' demands for increased output power and brightness, compact pump configurations, and reduced overall system cost.

The module features the latest generation of multimode pump laser chips from the Bookham Zurich facility, enabling the increase in power from the 20W module launched in September 2008. The module is hermetically sealed and incorporates a floating anode and cathode. Its compact design reduces the footprint of fiber laser pump stages.

The module is tailored for high volume manufacturing in the Bookham packaging and assembly facility in Shenzhen, China. The future proof solution allows for scaling of output power through integration of future generation chips or increasing the number of chips used, allowing fiber laser manufacturers to seamlessly upgrade pump stages or reduce the number of pumps required in order to lower system costs. The 25W pump module is on show for the first time on the Bookham booth (#1515) at Photonics West this week.

"This is a significant evolution in the development of our portfolio of high power pump modules for the fiber laser market," said Gunnar Stolze, Director High Power Laser Marketing and Sales at Bookham. "We continue to reinforce our leadership, and to enable fiber laser manufacturers to be competitive in terms of power, reliability, and cost with this breakthrough 25W multi-emitter module."

In addition to showing its new fiber laser pump modules and other high power laser diodes at Photonics West 2009, Bookham will be presenting two technical papers at associated symposium LASE 2009: 'Improved brightness on broad-area single emitter (BASE) modules', and 'Power scaling of bars toward 80mW per 1um stripe width reliable output power'.
