Pushing the Boundaries of Single-Mode Fiber Laser Technology

For more than 35 years, IPG has remained dedicated to advancing fiber laser technology and continuously challenging conventional expectations of laser performance.

The introduction of the YLR-8000-SM marks a significant milestone in the evolution of high-power single-mode fiber lasers. Delivering up to 8 kW of continuous-wave output power while maintaining exceptional beam quality (M² < 1.1), the YLR-8000-SM successfully combines ultra-high power with true single-mode performance.

In laser applications, beam quality plays a critical role in determining energy concentration, focusability, and processing precision. Historically, maintaining ideal single-mode characteristics at increasing power levels has presented a major technical challenge. Through innovative design and advanced system integration, the YLR-8000-SM overcomes these limitations and establishes a new benchmark for industrial single-mode laser performance.

World-Leading Brightness and Diffraction-Limited Beam Quality

The YLR-8000-SM delivers world-leading brightness and diffraction-limited beam quality, enabling laser energy to be concentrated into extremely small focal spots with exceptional efficiency.

These capabilities provide higher processing precision and improved manufacturing performance across a wide range of applications. Customers can achieve enhanced results in existing processes while exploring new opportunities enabled by the laser's unprecedented combination of power and beam quality.

In addition to its outstanding performance, the YLR-8000-SM features a compact design that offers greater flexibility for system integration, helping manufacturers efficiently deploy high-performance laser solutions in demanding production environments.

Expanding Possibilities for Advanced Manufacturing and Photonics Applications

Combining high power, exceptional brightness, and superior single-mode performance, the YLR-8000-SM supports a broad range of precision manufacturing and advanced photonics applications.

In materials processing, key applications include:

• Precision cutting
• Precision welding
• Surface texturing
• Additive manufacturing (3D printing)

Its exceptional beam quality enables smaller focal spots and higher energy density, supporting the demanding precision and quality requirements of advanced manufacturing processes.

Beyond materials processing, the YLR-8000-SM is well suited for remote processing applications and serves as an ideal light source for LiDAR, remote sensing, and directed energy applications. These capabilities open new opportunities across a diverse range of industries and emerging technologies.

Recognition by the Global Photonics Community

The 2026 SPIE Prism Awards featured 24 finalist products across multiple technology categories, including lasers, quantum technologies, biophotonics, sensors, and imaging systems.

Among this highly competitive field of innovations, the YLR-8000-SM was selected as the winner in the Lasers category. This achievement reflects not only the technical excellence of the product, but also the growing importance of high-power single-mode fiber laser technology in shaping the future of industrial and photonics applications.

For IPG, this award also continues a strong tradition of innovation recognized by the Prism Awards. In 2015, IPG received a Prism Award for its GLPN-500-R green fiber laser, and in 2020, its Laser Diode Direct (LDD) technology was named a Prism Award finalist. The recognition of the YLR-8000-SM further demonstrates IPG's ongoing commitment to advancing the state of the art in laser technology.

Driving the Future of Fiber Lasers Through Innovation

Since Dr. Valentin Gapontsev laid the foundation for modern fiber laser technology, innovation has remained at the core of IPG's mission. We believe that continuously expanding the boundaries of laser performance is essential to creating greater value for our customers and driving progress across industries.

The success of the YLR-8000-SM represents more than the introduction of a new product. It signifies a new stage in the development of high-power single-mode fiber laser technology and demonstrates what is possible when breakthrough engineering meets decades of expertise.

Looking ahead, IPG will continue investing in fiber laser and photonics innovation, helping customers improve manufacturing capabilities, expand application possibilities, and accelerate the development of next-generation industrial and photonics technologies.
