Gentec-EO – Laser Power Meter & Laser Energy Meters

TECHNICAL SHEET

A Gentec-EO calorimeter is the only reliable solution available for the largest and highest energy laser beams. Through cooperation with several leading research facilities around the world, Gentec-EO has become the expert in manufacturing, calibrating and servicing calorimeters for use in high energy inertial confinement fusion calorimetric measurement.

We work with a wide range of materials from surface coatings to the most robust volume absorbers to provide the best solution for your specific application.

Outstanding signal to noise ratios,

high sensitivity,

vacuum compatibility,

attention to detail and workmanship,
gained over 35 years of experience in thermal-based energy measurement make Gentec-EO the ideal choice for all your high energy measurement needs.

Using NIST traceable sources and proven calibration techniques, your Gentec-EO calorimeter is always the most accurate large aperture measurement device on the market. With calibration uncertainties of ±3%, and repeatabilities better than ±2% for very large beams, Gentec-EO offers the very best solution for extreme energy measurement and for balancing in multi laser systems.

We have designed calorimeters for 16 kJ beams. We have built them for beams as large as 420 x 427 mm in aperture size, to withstand pulse energy densities of more than 15 J/cm². We have also provided highly sensitive, large-aperture size calorimeters for beam energies as low as 50 mJ for the most delicate applications. Our calorimeters span the band from 190 nm to 25 microns.
