Coherent Inc., Santa Clara, Calif., recently enhanced its series of large-area, high-speed PowerMax-Pro laser detectors to enable power measurement of laser beams of up to 375W continuously, 600W for shorter durations, and modulated peak powers as high as 15 kW in intermittent (long-pulse) operation, according to the company. The PowerMax-Pro detectors, introduced in 2014, are based on Coherent’s proprietary thin-film sensor technology that combines the broad wavelength sensitivity, dynamic range and laser damage resistance of a thermopile with the response speed of a semiconductor photodiode.
