Coherent PM10K Power Sensor

Unique, high-accuracy sensor for high-power industrial lasers




Increase measurement speed of high-power lasers up to 5X with this unique sensor, which goes to 10 kW continuous/12 kW intermittent on beams up to 65 mm diameter.


Novel technology enables the PM10K+ to deliver power measurements of high-power lasers in under 3 seconds - faster than ever before. Compatible with lasers from the UV through the IR, it also offers convenience features for mounting and alignment.



  • Power handling up to 10 kW continuous and 12 kW intermittent
  • Fast 2 second measurement speed
  • BB+ Coating with high power density threshold
  • Broadband coating from 190 nm to 11 µm
  • Large 65 x 65 mm diameter active area
  • Flexible dovetail mount
  • DB25 + USB and RS232 configurations
  • Safety interlock monitors temp and water flow conditions

These 10 kW water-cooled laser power sensors feature a 65 mm x 65 mm sensor with the BB+ coating that can handle  power densities from 6 kW/cm² (at 1kW) to 2.7 kW/cm² (at 10 kW). The sensor can measure up to 10 kW continuously and  up to 12 kW on an intermittent basis. You can choose from USB + DB-25 or RS-232 communication options. DB-25 + USB sensor models are compatible with Coherent’s stand-alone power meters, which can be ordered separately.
