16 Aug 2013 Oclaro, Inc. (NASDAQ: OCLR), a tier-one provider and innovator of optical communications and laser solutions, today announced the BMU80, a high power fiber-coupled laser diode pump capable of delivering 80 W power in a 105um fiber. The high brightness pump enables fiber laser manufacturers to generate higher pump power levels using fewer modules, allowing them to increase pump block efficiency, design more compact pump configurations, and simplify their packaging.

The single-emitter based platform is available at output powers of 80 W with a 0.15NA or 65 W with < 0.14NA at 1kFITchip rating, making it the ideal solution for pumping of kilowatt and high power pulsed fiber lasers.
The 80 W pump module leverages a new generation of laser diode chip with increased efficiency above the previous chip generation. A proprietary optical scheme delivers light into the fiber with high- coupling efficiency, and a controlled under-filled NA along with a cladding mode stripping feature, which allows customers to increase reliability and reduce losses at the combiner. A compact, rugged housing offers superior thermal management. Automated alignment and manufacturing processes enable high volume with highest consistency in module-to-module performance.
The new multimode laser diode chip has endured a rigorous 4,000 hour multi-cell life-test under accelerated conditions, totalling 0.5 million accelerated device hours, and has already been integrated into an Oclaro mid power fiber laser pump module, allowing a seamless upgrade from 25 W to 30 W.
"This is a significant evolution in the development of our portfolio of high power pump modules for the fiber laser market," said Yves LeMaitre, Chief Commercial Officer for Oclaro, Inc. "We continue to reinforce our leadership, and to enable fiber laser manufacturers to compete in terms of reliable power, efficiency, and cost, both with the new 80 W pump modules and upgraded 30 W products." |
