New records broken in high average power from a high energy laser; measured with Gentec-EO accuracy

Gentec-EO would like to congratulate the recent amazing work by the HiLASE team in Czechia, who improved on their previous record for the highest amount average power from an high-energy laser. HiLASE managed to produce 10 ns pulses with a whooping 145 J per pulse with a 1030-nm laser, which is 40% more than their previous record.

We at Gentec-EO are familiar with the measurement of kW continuous lasers, but a pulsed one with 145 J per pulse? Now that's something! HiLASE's ''Bivoj'' laser system is an elaborate system involving cryogenically cooled amplifiers and other intricate optical components to amplify the output from Diode Pumped Solid State Lasers (DPSSL) from a few millijoules to a mind-boggling 145 J.

Laser specifications change over time for many reasons and it causes problems accross all industries. Learn about how laser output measurement solves numerous problems in YOUR industry. Download the guide below.


Gentec-EO's high-accuracy laser beam measurement instruments help engineers, scientists and technicians in all sorts of laser applications from the factory to the hospital, laboratory and research center. Learn about our solutions for these measurement types:

Gentec-EO is proud to have provided the energy detectors used by HiLASE to make this achievement. One can see in the official HiLASE videos that a QE50LP-S-MB-D0 energy detector was the detector used to determine and put a number on this amazing feat.

The maximum measurable energy with a QE50 doesn't go that high, so it goes without saying that the measurement here is not picked up directly: the laser is sampled so that only a small fraction of the energy is actually being measured.

When the attenuation factor of this system is known, its reverse value can then be applied to the attenuated measurement to find the original energy level, before attenuation. This underlines how even the smallest detector can be used to measure the most powerful of lasers, when used smartly! We are glad to have contributed in our little way to this big project!
