Frequently Asked Questions

A Gentec-EO calorimeter is a reliable solution for measuring high energy laser beams. It is manufactured, calibrated, and serviced by Gentec-EO, which has become an expert in this field through cooperation with leading research facilities around the world.

A Gentec-EO calorimeter has outstanding signal to noise ratios, high sensitivity, vacuum compatibility, and attention to detail and workmanship. It is designed to work with a wide range of materials and can measure beam energies from 50 mJ to 16 kJ across a band from 190 nm to 25 microns.

A Gentec-EO calorimeter is the most accurate large aperture measurement device on the market, with calibration uncertainties of ±3% and repeatabilities better than ±2% for very large beams. It is calibrated using NIST traceable sources and proven calibration techniques.

Gentec-EO calorimeters are used for high energy inertial confinement fusion calorimetric measurement, as well as for balancing in multi laser systems. They are also used for laser fusion experiments, where they measure the energy delivered to the outer layer of a fuel target using high-energy beams of laser light.

Gentec-EO has built calorimeters for beams as large as 420 x 427 mm in aperture size, to withstand pulse energy densities of more than 15 J/cm2.
