Coherent has extended 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 15kW in intermittent (long pulse) operation.

PowerMax-Pro detectors, first 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. 

The new PowerMax-Pro HP model sensors will be particularly useful for materials processing applications based on high power fibre lasers, CO2 lasers, solid state lasers and direct diode lasers, including welding, drilling, engraving and heat treating.  

Another important application area is with the pulsed lasers used for various aesthetic and surgical medical applications, such as skin resurfacing, scar treatment, tattoo and pigment removal and hair removal. Typical lasers for these applications include Q switched Alexandrite, direct diode lasers, CO2 lasers and various other solid state lasers. In these uses, the ability to measure the temporal pulse profile of long pulses at low repetition rates, as well as pulse trains, ensures greater patient safety, more repeatable performance, and better compliance with FDA regulations.
