Coherent EnergyMax-USB Sensors

High performance sensor with high speed USB2.0 connectivity integrated within the sensor cable




EnergyMax-USB ‘meterless’ sensors contain miniaturised meter electronics and a high speed USB interface that are integrated within the sensor cable. Coherent’s entire range of high performance EnergyMax-USB sensors enable the measurement of the energy per pulse or average power of pulsed lasers from the nanojoule to the multi-joule level, over wavelengths from the deep ultraviolet through the far infrared, and from single pulses to repetition rates of 10 kHz (with measurements of every pulse).



  • USB connectivity
  • Fast 14-bit A/D converter and FPGA processor for high speed, accurate operation
  • Log every pulse up to 10 kHz directly to a file
  • Synchronised dual unit operation to support A/B ratiometry > 1 kHz every pulse
  • State-of-the-art EnergyMax Sensor Technology

Additionally, stacking (of up to four) EnergyMax sensors enables all connected units to share both internal and external triggers for synchronised operation, such applications such as pulse-to-pulse ‘A/B’ ratiometry.
