Bookham has launched a high power multi-emitter pump module capable of delivering 25W out of a 105µm fibre with 0.15NA.
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 solution allows for scaling of output power through integration of future generation chips or increasing the number of chips used, allowing fibre laser manufacturers to seamlessly upgrade pump stages or reduce the number of pumps required in order to lower system costs.
