Trung Quốc đạt được bước đột phá với công nghệ laser femtosecond công suất 100 terawatt, mở ra những triển vọng mới cho các ứng dụng phủ lớp bằng laser

Ngày 14 tháng 10 năm 2025

Recently, Chinese scientists achieved a significant breakthrough in laser technology. A research team from Wuhan successfully developed a revolutionary femtosecond laser device that not only demonstrated the astonishing ability to “write Chinese characters” in mid-air but also, and more importantly, opens up new development opportunities for Phủ lớp bằng laser công nghệ.

Femtosecond Laser Technology: A Breakthrough in Direct Air Imaging

Traditional laser technologies require the use of media such as dust or water mist to create visible optical effects. However, this innovative femtosecond laser technology uses ultra-short laser pulses to directly strip electrons from air molecules, converting them into glowing plasma, enabling visible 3D displays in any environment. During a demonstration at Wuhan Optics Valley’s Hongtuo Ultrafast Laser Joint Laboratory, researchers created 3D characters that could be viewed from any angle, even allowing users to “touch” these floating images with their hands.

Chief scientist Dr. Cao Xiangdong explained, “This new device enables us to achieve aerial imaging without using any physical medium. By focusing high-intensity laser pulses in the air to form glowing plasma and using a 3D scanner to precisely control the laser beam, we can construct various letters and patterns in mid-air.”

The Technological Advantage of Femtosecond Lasers and Their Potential Integration with Laser Cladding

The core of this technology lies in the femtosecond laser pulses, which last just one trillionth of a second. Despite their extremely short duration, these pulses achieve an impressive peak power of 100 terawatts. This unique combination of ultra-high intensity and low average power enables the device to possess powerful processing capabilities while remaining safe for use in everyday environments.

Notably, the ultra-high precision and minimal heat-affected zone of femtosecond lasers provide new possibilities for upgrading Công nghệ phủ lớp bằng laser. In precision laser cladding applications, femtosecond lasers are expected to enable more precise control over cladding layers. This could revolutionize Phủ lớp bằng laser for fine components, especially in repair ứng dụng.

The Future of Femtosecond Laser Technology in Laser Cladding

Dr. Cao Xiangdong’s team emphasized that this achievement is the result of over a decade of continuous research. Achieving direct imaging in air requires a laser energy density of 100 terawatts per square centimeter, a technical threshold that many similar studies have struggled to surpass. However, researchers believe there is still room for improvement, and by further refining the distribution of laser pulses, they aim to create brighter and larger full-color images in the future.

In terms of application prospects, the team particularly highlighted the potential of this technology in Phủ lớp bằng laser. Traditional Phủ lớp bằng laser processes typically use longer pulses, but the introduction of femtosecond lasers could create a new paradigm for ultra-precise Phủ lớp bằng laser. In medical device manufacturing, femtosecond laser-assisted Phủ lớp bằng laser technology could achieve micron-level precision coatings; in aerospace, this new laser cladding process could be used to repair high-value precision components.

Synergistic Effects Between Femtosecond Lasers and Laser Cladding

The breakthrough in femtosecond laser technology offers various improvements to the Quy trình phủ lớp bằng laser. On one hand, the extreme precision of femtosecond lasers can achieve cladding layer structures that were previously unattainable with traditional Phủ lớp bằng laser methods. On the other hand, the minimal heat-affected zone prevents thermal damage to the substrate material during the Phủ lớp bằng laser process. This combination could significantly extend the application of Phủ lớp bằng laser in emerging fields like microelectronics and biomedicine.

It is worth noting that the laboratory has already successfully applied femtosecond lasers to disinfection devices, which were verified by Wuhan University’s National Virus Laboratory. This technological transition also provides valuable insights for the industrialization of femtosecond lasers in Laser Cladding applications.

Technological Outlook and Development Path

As femtosecond laser technology continues to mature, its application depth and breadth in Phủ lớp bằng laser will expand. Researchers predict that within the next three to five years, femtosecond laser-assisted precision Phủ lớp bằng laser technology will be scaled up in high-value manufacturing sectors. This fusion of technologies will not only improve existing Phủ lớp bằng laser processes but may also give rise to entirely new application scenarios and business models.

This breakthrough not only showcases China’s leadership in the field of ultrafast lasers but also paves a new technical path for the innovative development of Phủ lớp bằng laser technology. As femtosecond lasers are deeply integrated with Laser Cladding processes, we can expect more technological breakthroughs and application innovations in precision manufacturing, medical devices, and aerospace.
