Measuring The Energy Of One Of The Most Powerful Lasers In The USA

A prominent research center developing one of the most powerful lasers in the United States partnered with Gentec-EO to measure high-energy laser beams effectively. The laser system, designed for fundamental physics research, demands precise energy monitoring at various beam path stages to ensure efficient performance and adherence to safety protocols. These measurements are critical as the laser’s high-power shots are limited, and failed experiments can significantly delay progress.

The center faced challenges such as extremely high power density, large beam sizes (up to 160 mm), and pulses in the femtosecond range. Gentec-EO’s team collaborated with the researchers to recommend tailored solutions, leveraging their QE pyroelectric laser energy detectors for small-to-medium beams and custom calorimeters for large beams in the amplification stage.

The QE detectors, featuring broad wavelength compatibility and high energy thresholds, were paired with Gentec-EO’s INTEGRA PC interface for easy data logging and analysis. For the larger beam measurements, custom calorimeters were developed, incorporating specialized materials and precise calibrations to meet unique requirements.

This partnership has proven fruitful, with the research center using Gentec-EO’s solutions for over a decade, valuing their reliability and durability. As the laser nears its first operational shot, Gentec-EO’s contributions continue to enable critical advancements in laser research, cementing their reputation as leaders in laser beam measurement technology.
