Coherent has extended its series of large area, high speed, PowerMax-Pro laser detectors to enable power measurement of continuous-wave modulated laser beams of 3kW and 5kW peak power.
PowerMax-Pro detectors combine the broad wavelength sensitivity, dynamic range and laser damage resistance of a thermopile with the response speed of a semiconductor photodiode.
The new PowerMax-Pro kW models will be particularly useful for materials processing applications based on high power fibre lasers, CO2 lasers and solid-state lasers, including welding, cutting, drilling, and engraving.
PowerMax-Pro delivers a stable kilowatt power reading within microseconds with no overshoot. The PowerMax-Pro kW sensor’s innovative optical design also traps more than 99 per cent of the incident light inside the enclosure, eliminating the problem of back reflection. When used with a direct QBH fibre adapter option, 100 per cent of the incident light is captured, resulting in a Class 1 measurement system.
