New high-speed pulse energy detectors for high repetition rate lasers up to 10 kHz

Quebec City, CANADA – Gentec-EO has announced the QE12HR and QE25HR pulse energy detectors. Designed for use with Q-switched lasers and pulsed laser diodes, these sensors feature an improved temporal response to accurately measure pulse-to-pulse energy at high repetition rates up to 10 kHz.

Ideal for use in micromachining, range finding and research applications, the QE-HR energy detectors operate over a wide range of wavelengths, energy densities, and repetition rates. They are available in a variety of configurations so you can pick the best combination for your application:

  • A choice of 2 aperture sizes for different energy levels and beam sizes.
  • A choice of optical absorber materials: MB for high damage thresholds, MT for the fastest repetition rates.
  • Heatsink cooling for high average powers.
  • Built-in diffuser for high energy densities.

Each detector is calibrated across the full spectrum, from the UV to the NIR, to ensure the highest levels of accuracy.

Laser specifications change over time for many reasons and it causes problems accross all industries. Learn about how laser output measurement solves numerous problems in YOUR industry. Download the guide below.


Gentec-EO's high-accuracy laser beam measurement instruments help engineers, scientists and technicians in all sorts of laser applications from the factory to the hospital, laboratory and research center. Learn about our solutions for these measurement types:

While QE12HR and QE25HR pulse energy detectors can be operated with any of Gentec-EO’s displays and PC interfaces, only the U-LINK PC interface will capture all pulses at 10 kHz, no missing points.
