Laser physics holds the potential to unlock answers to some of science’s most profound questions. Leonardo Electronics US is proud to collaborate with leading institutions and researchers driving this frontier, supporting their work through prototype development, low-rate custom laser diode production, system testing, and qualification



As the race for fusion energy continues, Leonardo already delivers products relevant to IFE, such as megawatt-class laser diode array modules, homogenized pump engines, and the patented and field-proven fluid-cooled laser diode array (T6) devices.
- Leonardo has shipped over 50,000 T6 devices. The T6 is the benchmark fluid-cooled, monolithic laser diode array, delivering high performance, a rugged design, and thermal efficiency in a compact, scalable package.
- The homogenized pump engine is highly customizable in beam shape, size, wavelength, and integration level with a compact and modular design to energize any size and type of gain material. The system is field-proven and integrates seamlessly into larger lasers, demonstrating its performance, delivering results, and leaving customers satisfied.
- Finally, the megawatt-class laser diode array modules have been operating in the field for nearly a decade and are capable of delivering up to 2 MW of peak power, featuring rugged packaging, beam collimation, and individually powered arrays for fine-tuned control.
MegaWatt at ELI Beamlines
In collaboration with ELI Beamlines and Lawrence Livermore National Laboratory, Leonardo Electronics US played a pivotal role in developing the MegaWatt, now operating as L3 at ELI Beamlines in the Czech Republic. Leonardo developed and manufactured the four 800 kW diode pump modules that power the main amplifier in this laser. L3 is helping to advance a variety of research topics. Among these are laser wakefield acceleration to create a variety of high-energy particle beams, laser-matter interaction for basic research, and exploring novel techniques to exploit fusion energy.
UKRI
Leonardo Electronics US has partnered with UK Research and Innovation (UKRI) to further discoveries and research in laser physics. Our most recent project involved designing and building a laser diode system for use in a high-energy laser amplifier system as part of the new Extreme Photonics and Applications Centre (EPAC), run by the Science and Technology Facilities Council’s Central Laser Facility (CLF). Based at STFC’s Rutherford Appleton Laboratory in Oxfordshire, UK, the system comprises two optical modules that deliver up to 35 J each at 10 Hz, with a peak power of 29 kW. We are proud to partner with universities and laboratories worldwide to create advancements in emerging applications.
