Coherent Expands PowerMax™ Line with PM15k+ High-Power Laser Sensor and New Backscatter Shield for PM10k+
SAXONBURG, Pa., June 16, 2025 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE:COHR), a global leader in photonics, today announced the expansion of its industry-leading PowerMax™ sensor portfolio with two new innovations: the PM15K+ high-power laser sensor and a new backscatter shield option for the PM10K+. These new solutions address the growing demand for accurate, efficient, and safe measurement of high-power laser systems in industrial environments.
The PM15K+ sensor is designed to measure continuous laser power up to 15 kW, with the capability to handle intermittent power up to 20 kW. Featuring a large 100 mm x 100 mm active area, it accommodates wide beam diameters typically found in high-power diode and fiber laser systems. With a typical response time of just 5 seconds, the PM15K+ is ideal for high-throughput industrial settings that require fast, reliable laser power measurements.
Coherent also introduced a major enhancement to its popular PM10K+ sensor—a backscatter shield that dramatically improves measurement accuracy and safety. The shield reduces reflected laser energy from 10–15% down to 1% or less, capturing stray laser light that might otherwise interfere with surrounding equipment or personnel. It features a 65 mm round input aperture and integrates seamlessly with existing PM10K+ systems.
"These new innovations reflect our commitment to advancing the state of laser measurement," said Dr. Torsten Rauch, Senior Vice President, Solid State Business Unit. "With the PM15K+ and backscatter shield for the PM10K+, users now have more tools to measure high-power lasers accurately, efficiently, and safely."
Both new offerings are generally available and are fully compatible with the Coherent LabMax-Pro and PowerMax-Pro systems, supporting a wide range of industrial manufacturing, scientific, and medical laser applications.
