The L3-HAPLS laser system, developed by Lawrence Livermore National Laboratories and powered by EVANSCAPS from Evans Capacitor Company, has been deemed fully operational and is ready for use.
In June 2017, the L3-HAPLS Laser, the world’s most advanced and highest average power, diode-pumped petawatt laser system, was delivered to ELI Beamlines Research Center in Dolní Břežany, Czech Republic. After integration into the ELI Beamlines facility, the laser was evaluated by an international peer review group and deemed fully integrated and operational. The system is now ready for use in its first experiments.
The L3-HAPLS Laser was designed, developed and constructed by Lawrence Livermore National Laboratory. Development of the HAPLS required high power in the pulser. Each pulser contains its own local energy storage capacitor bank consisting of 3 Evans Capacitor’s TDD3125452 4500μF/125VDC tantalum “Hybrid” capacitors. According to the development engineers at LLNL, “The capacitors deserve special note as they are a major enabling technology that reduce the volume of the capacitor bank by at least a factor of three while providing better ripple current characteristics and superior cooling compared to standard electrolytic devices. The use of these capacitors allows the incorporation of 100J of energy storage in approximately 3.5 cubic inches.”
The L3-HAPLS laser’s ability to focus high intensity petawatt peak power pulses on a target will enable unparalleled access to variety of new research projects in fields including time-resolved proton and X-ray radiography and laboratory astrophysics. It will also help research basic science and medical applications for cancer treatments and industrial applications such as nondestructive material evaluation and laser fusion.
