Coherent introduces 1200 mW pump laser module


The laser manufacturer Coherent has announced a new pump laser module with 1200 mW of output power in a 10-pin butterfly package. The company says this is the industry’s first such module.

Rapid advances in optical communications technologies are reaching the theoretical limits of fibre-optic capacity and driving the expansion of transmission windows into the extended C- and L-bands. The 1200 mW pump lasers from Coherent provide the additional power needed to amplify the larger number of channels supported by these next-gen ultra-broadband optical transmission systems while meeting the stringent reliability requirements of these advanced networks.

“This is the highest-power commercially available pump laser module on the market, fully qualified, and available today,” said Dr. Beck Mason, EVP, Telecommunications Business Unit. “Together with our new dual-chip pump laser module, previously announced at OFC 2023, this 1200 mW module gives us the leading portfolio of high-power pump solutions. Customers can count on Coherent as a trusted supplier of pump lasers, generation after generation. This 1200 mW pump is built upon chip developments and module packaging solutions that have been continuously advanced over the past 28 years, with nearly eight million units shipped.”

The pump laser module, which is available in standard and low-power-consumption versions, aims to help designers to overcome increased losses in complex amplifier and system architectures and achieve higher-performance, cost-effective, and reliable amplifier designs. Available in a range of power specifications up to and including 1200 mW, the product allows single pump laser solutions in applications historically requiring two separate lasers.
