Product Portfolio

  • Whether you are interested in measuring your laser power, laser energy or conduct beam diagnostics to know all the characteristics of your laser, we have a measurement instrument for that.

      • 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 military 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.

            • NEW: HP100A-50KW-GD to measure extremely 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!

        • We offer a wide range of laser power meters and power detectors to measure from picowatts to multi-kilowatts. The right product for you highly depends on your laser specifications and measurement needs.


            • Gentec-EO offers a wide range of high accuracy laser power meters suitable for all professional uses that require a precision measurement, from industrial to medical and even scientific uses.

              Depending on your laser specifications and needs, you can purchase a laser power measurement system by choosing a power detector and an aquisition/readout device separately or you can go with an all-in-one, portable laser power meter.

              We recommend that you start by selecting the power detector that meets your requirements and then choose a compatible acquisition/readout device.


            • With our standard power detector offering, you can measure power from 0.3 nW to 100,000 W. To measure such a wide range, we rely on five state-of-the-art technologies:
