The quest for clean, limitless energy is taking monumental leaps forward with the National Ignition Facility’s (NIF) groundbreaking achievement in Laser Fusion and our team played a pioneering role in its success.
Researchers at NIF have successfully achieved energy gain, where the energy output of a fusion reaction exceeded the energy input used to trigger it. This remarkable advancement places humanity on the brink of realizing a future powered by laser fusion—an energy source that could change the trajectory of human progress and significantly mitigate the challenges of climate change.
In December 2022, scientists at the National Ignition Facility achieved this milestone in fusion energy by reaching fusion ignition—a self-sustaining fusion reaction that produced more energy than was consumed in the process. The initial experiment demonstrated a net energy gain of 154%, generating 3.15 megajoules (MJ) of fusion energy from 2.05 MJ of laser input. Building on this monumental achievement, subsequent experiments have pushed the boundaries even further. Notably, in February 2024, researchers achieved a stunning 136% energy surplus, producing 5.2 MJ of output from just 2.2 MJ of input. These results underscore the immense potential of fusion energy as a clean, limitless source of power and illuminate a future defined by revolutionary advancements in sustainable energy innovation.
At the core of these achievements lies the principle of nuclear fusion, the same process that powers our Sun. By replicating these reactions on Earth, we can unlock a source of energy that is virtually inexhaustible, does not produce long-lived radioactive waste, and has minimal environmental impact. NIF’s historic experiment utilized its state-of-the-art facility to fire 192 high-powered lasers at a tiny capsule containing hydrogen isotopes. The intense heat and pressure created conditions similar to those in the core of a star, triggering the fusion process. The result? An unprecedented moment in modern science—an energy gain that marks the dawn of a new era.

Focused Energy's approach is the closest to the concept that was scientifically proven on NIF and the design focuses on components that are modular and can be mass produced, with power plant grade reliability, redundancy and easy-to-service components.
Beyond the scientific triumph, NIF's breakthrough sends ripples across the globe. It solidifies laser fusion's potential as a viable contributor to the world’s energy portfolio. More importantly, it underscores humanity’s capacity for innovation and perseverance in tackling even the most complex, grand challenges. While significant work remains to transition this achievement into a scalable and commercially viable energy source, one of the most significant hurdles has been achieved.
NIF’s success represents a bold step toward reshaping how we power our world. The vision of clean, abundant energy that can fuel economic growth while safeguarding our planet is no longer a distant dream—it is becoming an attainable reality. This historic milestone serves as a testament to the power of science, ingenuity, and the relentless optimism that drives humanity toward a brighter future.
Our approach is the closest architecture to the only scientifically proven Laser Fusion system. Our design focuses on manufacturability, with components that can be mass-produced and easily shipped. It will also offer power plant-grade reliability—modulatory creates the highest reliability and serviceability of any fusion system.
We use Deuterium-Tritium fusion fuel and have one of the only target labs in the world to design and optimize fusion fuel. Deuterium-Tritium originates from sea water & lithium and is the only fuel to achieve controlled ignition and gain.
