Laser Detector Line Extended to Higher Powers The company has extended its series of large area, high-speed, Power- Max-Pro laser detectors to enable power measurement of laser beams up to 375 W continuously, 600 W for shorter durations, and modulated peak powers as high as 15 kW in intermittent operation. The detectors are based on the company’s 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. The new HP model sensors are useful for materials processing applications based on high-power fiber lasers, CO2 lasers, solid-state lasers, and direct diode lasers, including welding, drilling, engraving, and heat treating. The ability to frequently sample CW laser power and pulsed laser energy results in increased throughput and improved process control.
