Chinese military scientists at the National University of Defence Technology in Changsha, Hunan province, have announced a “huge breakthrough” in laser weapon technology. According to a report by the South China Morning Post (SCMP), the team has developed a new cooling system that completely eradicates the harmful heat produced by high-energy laser operation, allowing these weapons to function “infinitely.”

This development could be a significant turning point in laser weapon technology, solving a problem that has been a major technical barrier for over six decades. The new cooling technology ensures that laser beams can be produced and maintained indefinitely without any interruption or loss in performance.

The cooling system works by removing heat from inside the laser weapon while limiting turbulence and vibration. It also enhances mirror cleaning through improved structures and optimal gas flow. The result is a weapon with extended engagement times, increased range and damage, and reduced logistics and costs.

The team, led by laser weapon scientist Yuan Shengfu, published a paper on August 4 in Acta Optica Sinica, a Chinese-language peer-reviewed journal, stating: “This is a huge breakthrough in improving the performance of high-energy laser systems. High-quality beams can be produced not only in the first second but also maintained indefinitely.”

The implications of this development are profound. Since the invention of the first ruby laser in 1960, scientists and military experts have been working towards transitioning from kinetic energy to laser energy, envisioning laser beams as “death rays” that could instantly eliminate targets. However, the application of high-energy laser systems has been largely unsuccessful due to technical challenges, particularly the heat buildup.

The Chinese team’s breakthrough could significantly alter the dynamics of modern warfare. The appearance of this weapon may introduce new challenges to missile sensors, and its potential applications are vast. Laser guns, capable of firing beams to divert homing missiles, have been conceptualized for various high-end military vehicles, including Air Force One and Apache attack helicopters.

This development comes at a time when laser weapon development is accelerating, driven by increasing arms competition between the West and China. The new technology, with its ability to generate laser beams without interruption or degradation, could make lasers a more viable and formidable tool on the battlefield.


The breakthrough also raises important questions about the global arms landscape and how this technology might be deployed, controlled, and regulated. It underscores China‘s commitment to innovation in military technology and its position as a leading player in shaping the future of warfare.
