PowerMax-Pro (Patent #9,059,346) represents a dramatic technological advancement in laser power sensing that combines the broad wavelength sensitivity, dynamic range and laser damage resistance of a thermopile with the response speed of a semiconductor photodiode. This high-speed, thin film sensor technology for laser power measurement (50 mW to 15 kW). Its unique thermal flow design enables fast, high power measurmeent, with high damage resistance. The sensor is so fast, less than ten microseconds in the case of the “HD” version, that users can trace the pulse shape of modulated lasers at pulse repetition frequencies up to 25 kHz.
