In early 2008, researchers at the University of Michigan’s laboratory achieved a major breakthrough by developing a laser that was twice as powerful as any existing laser globally at the time. This advancement marked a significant step forward in high-energy laser technology.
The "Dingli" laser system, which is based on a titanium-doped sapphire design, was enhanced with additional amplifiers to boost its power output. The system occupies multiple chambers and works by capturing light feedback between mirrors and optical components, focusing energy effectively. It can emit a powerful pulse every 10 seconds. Before the upgrade, Dingli had a maximum output of 50 terawatts (5 × 10¹³ watts), but after adding the amplifier, it reached an impressive 300 terawatts (3 × 10¹ⴠwatts). The laser's intensity can reach up to 2 × 10²² watts per square centimeter, making it capable of concentrating energy equivalent to focusing sunlight from across the Earth into a single grain of sand. The pulse lasts only 30 femtoseconds, yet it can focus its energy onto a spot just 1.3 micrometers in diameter—about one percent the width of a human hair.
On July 5, 2012, the U.S. National Ignition Facility made history by firing 192 lasers simultaneously, combining them into a single pulse that generated 500 terawatts of peak power. This was more than 1,000 times greater than the total electricity consumed in the U.S. at any given moment. The pulse was aimed at a 2 mm target and lasted for 23 billionths of a second. This milestone was crucial for nuclear fusion research, as it brought scientists closer to replicating the energy processes found in hydrogen bombs.
Edward Moses, director of the National Ignition Facility, called the achievement a key step toward clean fusion energy. Richard Patraso, a senior scientist at MIT, praised the 500 terawatt pulse as an extraordinary accomplishment, noting that it replicated conditions similar to those found deep within stars. Such experiments are vital for advancing our understanding of fusion and pushing the boundaries of science.
Since the 1950s, scientists have sought to control the fusion process seen in hydrogen bombs. Fusion ignition, if achieved, would create a self-sustaining reaction that releases far more energy than is used. Despite the short duration of these laser pulses, the energy required is stored in large capacitors, making the process feasible. The successful operation of 192 lasers at once marked a historic milestone for the U.S. National Ignition Program, showing progress toward controlled fusion energy.
