    Gentec-EO webinar: From photons to nuclear fusion: How to measure energy in any laser system

    Does your laser system always produce the exact same energy output? One may be tempted to assume that lasers always produce energy as per their specifications and that it never changes over time. The reality is often very different.

  • Gentec-EO QE95 Energy Detectors helped demonstrate the highest peak power capability in the world

    Gentec-EO QE95 Energy Detectors helped demonstrate the highest peak power capability in the world

    Researchers from the Extreme Light Infrastructure Nuclear Physics (ELI-NP) and Thales recently demonstrated that the two-arm hybrid high-power laser system (HPLS) is able to deliver 2 × 10 PW femtosecond pulses.

    The HPLS is composed of multiple pulse amplifiers and compressors, and at the end of this system is a beam-steering periscope with a leaky mirror that transmits a fraction of the beam to diagnostics equipment.

    The energy meter, a QE95 detector, allowed the authors to obtain data about the HPLS's final output stage. They were able to characterize the laser's extraction efficiency and show that the system could reach up to 327 J per pulse, with a duration of merely 23 fs. They also used the energy meter to demonstrate the reliability of the system, by measuring its repetition rate and pulse-to-pulse stability.

    This achievement is a new milestone in the development of high-power laser systems, and Gentec-EO is proud to have played a small part in it.

    The paper describing the results is: "High-energy hybrid femtosecond laser system demonstrating 2 × 10 PW capability" by Lureau et al. Published online by Cambridge University Press:  15 December 2020

    It is available online here. 

    Image above shows the Gentec-EO QE95LP-S-MB-D0 Pyroelectric detector for laser energy measurement up to 35 J.

    Gentec-EO Energy Detectors

    Gentec-EO's pyroelectric energy meters cover a very wide range, going from nanojoules to several tens of joules per pulse. They also come in various sizes, from 8 mm to 95 mm in diameter and most of them are available with an optional attenuator.

    For a list of all available models, please read further below.

    An extra mounting hole with metric thread was recently added to the Gentec-EO detectors with a cylindrical housing. This second mounting hole makes it simpler to integrate these detectors in any optical system.
