NEW: HP100A-50KW-GD to measure extremely high-power laser beams

Quebec City, QC, Canada, January 11, 2024 - Gentec-EO, a provider of laser beam measurement instruments, has announced a new measurement solution for high-power laser beams up to 50 kW.

The HP100A-50KW-GD laser power detector was designed mainly for high-power laser and laser system manufacturers, factories that cut thick metal parts with high-power lasers, and defense applications.

With its gold reflector cone and back-reflection reducing geometry, the HP100A-50KW-GD traps > 97 % of the incident light and can handle up to 50 kW of continuous laser power. The very low back-reflections of the detector ensure a safer working environment with high-power lasers. This detector can also handle the high intensities of small beams.

Practical design for high-power laser beams

  • The gold cone design allows for very high damage thresholds of 25 kW/cm2.
  • Very low back-reflections, < 2.5 %, make it safe to use even at 50 kW.
  • Compact: less than 20 cm thick.
  • Serial commands available via USB. Other connectors are available on request.
  • Water flow and temperature are monitored in real-time and displayed continuously, so you won’t risk burning out the detector if the cooling is interrupted.
  • Customizable design: tell us your needs!

Log your measurements on a Gentec-EO display or on your PC

Each detector comes with both a DB15 connector for use with a Gentec-EO display (MAESTRO, MIRO ALTITUDE, TUNER, or UNO) and a USB output for direct connection to a PC. Our proprietary software is available for free for all our customers. Other connectors are available upon request.
